+# Contributing
+
+### Building
+
+You need either [Docker](https://github.com/docker/docker) and `make` (Method 1), or `go` and `glide` (Method 2) in order to build traefik.
+
+#### Method 1: Using `Docker` and `Makefile`
+
+You need to run the `binary` target. This will create binaries for Linux platform in the `dist` folder.
+
+```bash
+$ make binary
+docker build -t "traefik-dev:no-more-godep-ever" -f build.Dockerfile .
+Sending build context to Docker daemon 295.3 MB
+Step 0 : FROM golang:1.7
+ ---> 8c6473912976
+Step 1 : RUN go get github.com/Masterminds/glide
+[...]
+docker run --rm  -v "/var/run/docker.sock:/var/run/docker.sock" -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/emile/dev/go/src/github.com/containous/traefik/"dist":/go/src/github.com/containous/traefik/"dist"" "traefik-dev:no-more-godep-ever" ./script/make.sh generate binary
+---> Making bundle: generate (in .)
+removed 'gen.go'
+
+---> Making bundle: binary (in .)
+
+$ ls dist/
+traefik*
+```
+
+#### Method 2: Using `go` and `glide`
+
+###### Setting up your `go` environment
+
+- You need `go` v1.7+
+- It is recommended you clone Træfɪk into a directory like `~/go/src/github.com/containous/traefik` (This is the official golang workspace hierarchy, and will allow dependencies to resolve properly)
+- This will allow your `GOPATH` and `PATH` variable to be set to `~/go` via:
+```
+$ export GOPATH=~/go
+$ export PATH=$PATH:$GOPATH/bin
+```
+
+This can be verified via `$ go env`
+- You will want to add those 2 export lines to your `.bashrc` or `.bash_profile`
+- You need `go-bindata` to be able to use `go generate` command (needed to build) : `$ go get github.com/jteeuwen/go-bindata/...` (Please note, the ellipses are required)
+
+###### Setting up your `glide` environment
+
+- Glide can be installed either via homebrew: `$ brew install glide` or via the official glide script: `$ curl https://glide.sh/get | sh`
+
+The idea behind `glide` is the following :
+
+- when checkout(ing) a project, run `$ glide install -v` from the cloned directory to install
+  (`go get …`) the dependencies in your `GOPATH`.
+- if you need another dependency, import and use it in
+  the source, and run `$ glide get github.com/Masterminds/cookoo` to save it in
+  `vendor` and add it to your `glide.yaml`.
+
+```bash
+$ glide install --strip-vendor
+# generate (Only required to integrate other components such as web dashboard)
+$ go generate
+# Standard go build
+$ go build
+# Using gox to build multiple platform
+$ gox "linux darwin" "386 amd64 arm" \
+    -output="dist/traefik_{{.OS}}-{{.Arch}}"
+# run other commands like tests
+```
+
+### Tests
+
+##### Method 1: `Docker` and `make`
+
+You can run unit tests using the `test-unit` target and the
+integration test using the `test-integration` target.
+
+```bash
+$ make test-unit
+docker build -t "traefik-dev:your-feature-branch" -f build.Dockerfile .
+# […]
+docker run --rm -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/vincent/src/github/vdemeester/traefik/dist:/go/src/github.com/containous/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate test-unit
+---> Making bundle: generate (in .)
+removed 'gen.go'
+
+---> Making bundle: test-unit (in .)
++ go test -cover -coverprofile=cover.out .
+ok      github.com/containous/traefik   0.005s  coverage: 4.1% of statements
+
+Test success
+```
+
+For development purposes, you can specify which tests to run by using:
+```
+# Run every tests in the MyTest suite
+TESTFLAGS="-check.f MyTestSuite" make test-integration
+
+# Run the test "MyTest" in the MyTest suite
+TESTFLAGS="-check.f MyTestSuite.MyTest" make test-integration
+
+# Run every tests starting with "My", in the MyTest suite
+TESTFLAGS="-check.f MyTestSuite.My" make test-integration
+
+# Run every tests ending with "Test", in the MyTest suite
+TESTFLAGS="-check.f MyTestSuite.*Test" make test-integration
+```
+
+More: https://labix.org/gocheck
+
+##### Method 2: `go` and `glide`
+
+- Tests can be run from the cloned directory, by `$ go test ./...` which should return `ok` similar to:
+```
+ok      _/home/vincent/src/github/vdemeester/traefik    0.004s
+```
+- Note that `$ go test ./...` will run all tests (including the ones in the vendor directory for the dependencies that glide have fetched). If you only want to run the tests for traefik use `$ go test $(glide novendor)` instead.
+
+
+### Documentation
+
+The [documentation site](http://docs.traefik.io/) is built with [mkdocs](http://mkdocs.org/)
+
+First make sure you have python and pip installed
+
+```
+$ python --version
+Python 2.7.2
+$ pip --version
+pip 1.5.2
+```
+
+Then install mkdocs with pip
+
+```
+$ pip install mkdocs
+```
+
+To test documentation locally run `mkdocs serve` in the root directory, this should start a server locally to preview your changes.
+
+```
+$ mkdocs serve
+INFO    -  Building documentation...
+WARNING -  Config value: 'theme'. Warning: The theme 'united' will be removed in an upcoming MkDocs release. See http://www.mkdocs.org/about/release-notes/ for more details
+INFO    -  Cleaning site directory

-Traefik (pronounced _traffic_) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.
-Traefik integrates with your existing infrastructure components ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Marathon](https://mesosphere.github.io/marathon/), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), ...) and configures itself automatically and dynamically.
-Pointing Traefik at your orchestrator should be the _only_ configuration step you need.

+Træfɪk (pronounced like [traffic](https://speak-ipa.bearbin.net/speak.cgi?speak=%CB%88tr%C3%A6f%C9%AAk)) is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease.
+It supports several backends ([Docker](https://www.docker.com/), [Swarm](https://docs.docker.com/swarm), [Kubernetes](http://kubernetes.io), [Marathon](https://mesosphere.github.io/marathon/), [Mesos](https://github.com/apache/mesos), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Zookeeper](https://zookeeper.apache.org), [BoltDB](https://github.com/boltdb/bolt), [Eureka](https://github.com/Netflix/eureka), Rest API, file...) to manage its configuration automatically and dynamically.
 
 ## Overview
 
-Imagine that you have deployed a bunch of microservices with the help of an orchestrator (like Swarm or Kubernetes) or a service registry (like etcd or consul).
-Now you want users to access these microservices, and you need a reverse proxy.
+Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
+If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
 
-Traditional reverse-proxies require that you configure _each_ route that will connect paths and subdomains to _each_ microservice. 
-In an environment where you add, remove, kill, upgrade, or scale your services _many_ times a day, the task of keeping the routes up to date becomes tedious. 
+- domain `api.domain.com` will point the microservice `api` in your private network
+- path `domain.com/web` will point the microservice `web` in your private network
+- domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
 
-**This is when Traefik can help you!**
+But a microservices architecture is dynamic... Services are added, removed, killed or upgraded often, eventually several times a day.
 
-Traefik listens to your service registry/orchestrator API and instantly generates the routes so your microservices are connected to the outside world -- without further intervention from your part. 
+Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
 
-**Run Traefik and let it do the work for you!** 
-_(But if you'd rather configure some of your routes manually, Traefik supports that too!)_
+Here enters Træfɪk.
+
+![Architecture](docs/img/architecture.png)
+
+Træfɪk can listen to your service registry/orchestrator API, and knows each time a microservice is added, removed, killed or upgraded, and can generate its configuration automatically.
+Routes to your services will be created instantly.
+
+Run it and forget it!
+

+# Concepts
+
+Let's take our example from the [overview](https://docs.traefik.io/#overview) again:
+
+
+> Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
+> If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
+
+> - domain `api.domain.com` will point the microservice `api` in your private network
+> - path `domain.com/web` will point the microservice `web` in your private network
+> - domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
+
+> ![Architecture](img/architecture.png)
+
+Let's zoom on Træfɪk and have an overview of its internal architecture:
+
+
+![Architecture](img/internal.png)
+
+- Incoming requests end on [entrypoints](#entrypoints), as the name suggests, they are the network entry points into Træfɪk (listening port, SSL, traffic redirection...).
+- Traffic is then forwarded to a matching [frontend](#frontends). A frontend defines routes from [entrypoints](#entrypoints) to [backends](#backends).
+Routes are created using requests fields (`Host`, `Path`, `Headers`...) and can match or not a request.
+- The [frontend](#frontends) will then send the request to a [backend](#backends). A backend can be composed by one or more [servers](#servers), and by a load-balancing strategy.
+- Finally, the [server](#servers) will forward the request to the corresponding microservice in the private network.
+
+## Entrypoints
+
+Entrypoints are the network entry points into Træfɪk.
+They can be defined using:
+
+- a port (80, 443...)
+- SSL (Certificates, Keys, authentication with a client certificate signed by a trusted CA...)
+- redirection to another entrypoint (redirect `HTTP` to `HTTPS`)
+
+Here is an example of entrypoints definition:
+
+```toml
+[entryPoints]
+  [entryPoints.http]
+  address = ":80"
+    [entryPoints.http.redirect]
+    entryPoint = "https"
+  [entryPoints.https]
+  address = ":443"
+    [entryPoints.https.tls]
+      [[entryPoints.https.tls.certificates]]
+      certFile = "tests/traefik.crt"
+      keyFile = "tests/traefik.key"
+```
+
+- Two entrypoints are defined `http` and `https`.
+- `http` listens on port `80` and `https` on port `443`.
+- We enable SSL on `https` by giving a certificate and a key.
+- We also redirect all the traffic from entrypoint `http` to `https`.
+
+And here is another example with client certificate authentication:
+
+```toml
+[entryPoints]
+  [entryPoints.https]
+  address = ":443"
+  [entryPoints.https.tls]
+  clientCAFiles = ["tests/clientca1.crt", "tests/clientca2.crt"]
+    [[entryPoints.https.tls.certificates]]
+    certFile = "tests/traefik.crt"
+    keyFile = "tests/traefik.key"
+```
+
+- We enable SSL on `https` by giving a certificate and a key.
+- One or several files containing Certificate Authorities in PEM format are added.
+- It is possible to have multiple CA:s in the same file or keep them in separate files.
+
+## Frontends
+
+A frontend is a set of rules that forwards the incoming traffic from an entrypoint to a backend.
+Frontends can be defined using the following rules:
+
+- `Headers: Content-Type, application/json`: Headers adds a matcher for request header values. It accepts a sequence of key/value pairs to be matched.
+- `HeadersRegexp: Content-Type, application/(text|json)`: Regular expressions can be used with headers as well. It accepts a sequence of key/value pairs, where the value has regex support.
+- `Host: traefik.io, www.traefik.io`: Match request host with given host list.
+- `HostRegexp: traefik.io, {subdomain:[a-z]+}.traefik.io`: Adds a matcher for the URL hosts. It accepts templates with zero or more URL variables enclosed by `{}`. Variables can define an optional regexp pattern to be matched.
+- `Method: GET, POST, PUT`: Method adds a matcher for HTTP methods. It accepts a sequence of one or more methods to be matched.
+- `Path: /products/, /articles/{category}/{id:[0-9]+}`: Path adds a matcher for the URL paths. It accepts templates with zero or more URL variables enclosed by `{}`.
+- `PathStrip`: Same as `Path` but strip the given prefix from the request URL's Path.
+- `PathPrefix`: PathPrefix adds a matcher for the URL path prefixes. This matches if the given template is a prefix of the full URL path.
+- `PathPrefixStrip`: Same as `PathPrefix` but strip the given prefix from the request URL's Path.
+- `AddPrefix` : Add prefix from the request URL's Path.
+
+You can use multlple values for a rule by separating them with `,`.
+You can use multiple rules by separating them by `;`.
+
+You can optionally enable `passHostHeader` to forward client `Host` header to the backend.
+
+Here is an example of frontends definition:
+
+```toml
+[frontends]
+  [frontends.frontend1]
+  backend = "backend2"
+    [frontends.frontend1.routes.test_1]
+    rule = "Host:test.localhost,test2.localhost"
+  [frontends.frontend2]
+  backend = "backend1"
+  passHostHeader = true
+  priority = 10
+  entrypoints = ["https"] # overrides defaultEntryPoints
+    [frontends.frontend2.routes.test_1]
+    rule = "HostRegexp:localhost,{subdomain:[a-z]+}.localhost"
+  [frontends.frontend3]
+  backend = "backend2"
+    [frontends.frontend3.routes.test_1]
+    rule = "Host:test3.localhost;Path:/test"
+```
+
+- Three frontends are defined: `frontend1`, `frontend2` and `frontend3`
+- `frontend1` will forward the traffic to the `backend2` if the rule `Host:test.localhost,test2.localhost` is matched
+- `frontend2` will forward the traffic to the `backend1` if the rule `Host:localhost,{subdomain:[a-z]+}.localhost` is matched (forwarding client `Host` header to the backend)
+- `frontend3` will forward the traffic to the `backend2` if the rules `Host:test3.localhost` **AND** `Path:/test` are matched
+
+### Combining multiple rules
+
+As seen in the previous example, you can combine multiple rules.
+In TOML file, you can use multiple routes:
+
+```toml
+  [frontends.frontend3]
+  backend = "backend2"
+    [frontends.frontend3.routes.test_1]
+    rule = "Host:test3.localhost"
+    [frontends.frontend3.routes.test_2]
+    rule = "Path:/test"
+```
+
+Here `frontend3` will forward the traffic to the `backend2` if the rules `Host:test3.localhost` **AND** `Path:/test` are matched.
+You can also use the notation using a `;` separator, same result:
+
+```toml
+  [frontends.frontend3]
+  backend = "backend2"
+    [frontends.frontend3.routes.test_1]
+    rule = "Host:test3.localhost;Path:/test"
+```
+
+Finally, you can create a rule to bind multiple domains or Path to a frontend, using the `,` separator:
+
+```toml
+ [frontends.frontend2]
+    [frontends.frontend2.routes.test_1]
+    rule = "Host:test1.localhost,test2.localhost"
+  [frontends.frontend3]
+  backend = "backend2"
+    [frontends.frontend3.routes.test_1]
+    rule = "Path:/test1,/test2"
+```
+
+### Priorities
+
+By default, routes will be sorted (in descending order) using rules length (to avoid path overlap):
+`PathPrefix:/12345` will be matched before `PathPrefix:/1234` that will be matched before `PathPrefix:/1`.
+
+You can customize priority by frontend:
+
+```
+  [frontends]
+    [frontends.frontend1]
+    backend = "backend1"
+    priority = 10
+    passHostHeader = true
+      [frontends.frontend1.routes.test_1]
+      rule = "PathPrefix:/to"
+    [frontends.frontend2]
+    priority = 5
+    backend = "backend2"
+    passHostHeader = true
+      [frontends.frontend2.routes.test_1]
+      rule = "PathPrefix:/toto"
+```
+
+Here, `frontend1` will be matched before `frontend2` (`10 > 5`).
+
+## Backends
+
+A backend is responsible to load-balance the traffic coming from one or more frontends to a set of http servers.
+Various methods of load-balancing are supported:
+
+- `wrr`: Weighted Round Robin
+- `drr`: Dynamic Round Robin: increases weights on servers that perform better than others. It also rolls back to original weights if the servers have changed.
+
+A circuit breaker can also be applied to a backend, preventing high loads on failing servers.
+Initial state is Standby. CB observes the statistics and does not modify the request.
+In case the condition matches, CB enters Tripped state, where it responds with predefined code or redirects to another frontend.
+Once Tripped timer expires, CB enters Recovering state and resets all stats.
+In case the condition does not match and recovery timer expires, CB enters Standby state.
+
+It can be configured using:
+
+- Methods: `LatencyAtQuantileMS`, `NetworkErrorRatio`, `ResponseCodeRatio`
+- Operators:  `AND`, `OR`, `EQ`, `NEQ`, `LT`, `LE`, `GT`, `GE`
+
+For example:
+
+- `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window for a frontend
+- `LatencyAtQuantileMS(50.0) > 50`:  watch latency at quantile in milliseconds.
+- `ResponseCodeRatio(500, 600, 0, 600) > 0.5`: ratio of response codes in range [500-600) to  [0-600)
+
+To proactively prevent backends from being overwhelmed with high load, a maximum connection limit can
+also be applied to each backend.
+
+Maximum connections can be configured by specifying an integer value for `maxconn.amount` and
+`maxconn.extractorfunc` which is a strategy used to determine how to categorize requests in order to
+evaluate the maximum connections.
+
+For example:
+```toml
+[backends]
+  [backends.backend1]
+    [backends.backend1.maxconn]
+       amount = 10
+       extractorfunc = "request.host"
+```
+
+- `backend1` will return `HTTP code 429 Too Many Requests` if there are already 10 requests in progress for the same Host header.
+- Another possible value for `extractorfunc` is `client.ip` which will categorize requests based on client source ip.
+- Lastly `extractorfunc` can take the value of `request.header.ANY_HEADER` which will categorize requests based on `ANY_HEADER` that you provide.
+
+Sticky sessions are supported with both load balancers. When sticky sessions are enabled, a cookie called `_TRAEFIK_BACKEND` is set on the initial
+request. On subsequent requests, the client will be directed to the backend stored in the cookie if it is still healthy. If not, a new backend
+will be assigned.
+
+For example:
+```toml
+[backends]
+  [backends.backend1]
+    [backends.backend1.loadbalancer]
+      sticky = true
+```
+
+A health check can be configured in order to remove a backend from LB rotation
+as long as it keeps returning HTTP status codes other than 200 OK to HTTP GET
+requests periodically carried out by Traefik. The check is defined by a path
+appended to the backend URL and an interval (given in a format understood by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration)) specifying how
+often the health check should be executed (the default being 30 seconds). Each
+backend must respond to the health check within 5 seconds.
+
+A recovering backend returning 200 OK responses again is being returned to the
+LB rotation pool.
+
+For example:
+```toml
+[backends]
+  [backends.backend1]
+    [backends.backend1.healthcheck]
+      path = "/health"
+      interval = "10s"
+```
+
+## Servers
+
+Servers are simply defined using a `URL`. You can also apply a custom `weight` to each server (this will be used by load-balancing).
+
+Here is an example of backends and servers definition:
+
+```toml
+[backends]
+  [backends.backend1]
+    [backends.backend1.circuitbreaker]
+      expression = "NetworkErrorRatio() > 0.5"
+    [backends.backend1.servers.server1]
+    url = "http://172.17.0.2:80"
+    weight = 10
+    [backends.backend1.servers.server2]
+    url = "http://172.17.0.3:80"
+    weight = 1
+  [backends.backend2]
+    [backends.backend2.LoadBalancer]
+      method = "drr"
+    [backends.backend2.servers.server1]
+    url = "http://172.17.0.4:80"
+    weight = 1
+    [backends.backend2.servers.server2]
+    url = "http://172.17.0.5:80"
+    weight = 2
+```
+
+- Two backends are defined: `backend1` and `backend2`
+- `backend1` will forward the traffic to two servers: `http://172.17.0.2:80"` with weight `10` and `http://172.17.0.3:80` with weight `1` using default `wrr` load-balancing strategy.
+- `backend2` will forward the traffic to two servers: `http://172.17.0.4:80"` with weight `1` and `http://172.17.0.5:80` with weight `2` using `drr` load-balancing strategy.
+- a circuit breaker is added on `backend1` using the expression `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window
+
+# Configuration
+
+Træfɪk's configuration has two parts: 
+
+- The [static Træfɪk configuration](/basics#static-trfk-configuration) which is loaded only at the beginning. 
+- The [dynamic Træfɪk configuration](/basics#dynamic-trfk-configuration) which can be hot-reloaded (no need to restart the process).
+
+
+## Static Træfɪk configuration
+
+The static configuration is the global configuration which is setting up connections to configuration backends and entrypoints. 
+
+Træfɪk can be configured using many configuration sources with the following precedence order. 
+Each item takes precedence over the item below it:
+
+- [Key-value Store](/basics/#key-value-stores)
+- [Arguments](/basics/#arguments)
+- [Configuration file](/basics/#configuration-file)
+- Default
+
+It means that arguments override configuration file, and Key-value Store overrides arguments.
+
+### Configuration file
+
+By default, Træfɪk will try to find a `traefik.toml` in the following places:
+
+- `/etc/traefik/`
+- `$HOME/.traefik/`
+- `.` *the working directory*
+
+You can override this by setting a `configFile` argument:
+
+```bash
+$ traefik --configFile=foo/bar/myconfigfile.toml
+```
+
+Please refer to the [global configuration](/toml/#global-configuration) section to get documentation on it.
+
+### Arguments
+
+Each argument (and command) is described in the help section:
+
+```bash
+$ traefik --help
+```
+
+Note that all default values will be displayed as well.
+
+### Key-value stores
+
+Træfɪk supports several Key-value stores:
+
+- [Consul](https://consul.io)
+- [etcd](https://coreos.com/etcd/)
+- [ZooKeeper](https://zookeeper.apache.org/) 
+- [boltdb](https://github.com/boltdb/bolt)
+
+Please refer to the [User Guide Key-value store configuration](/user-guide/kv-config/) section to get documentation on it.
+
+## Dynamic Træfɪk configuration
+
+The dynamic configuration concerns : 
+
+- [Frontends](/basics/#frontends)
+- [Backends](/basics/#backends) 
+- [Servers](/basics/#servers) 
+
+Træfɪk can hot-reload those rules which could be provided by [multiple configuration backends](/toml/#configuration-backends).
+
+We only need to enable `watch` option to make Træfɪk watch configuration backend changes and generate its configuration automatically.
+Routes to services will be created and updated instantly at any changes.
+
+Please refer to the [configuration backends](/toml/#configuration-backends) section to get documentation on it.
+
+# Commands
+
+Usage: `traefik [command] [--flag=flag_argument]`
+
+List of Træfɪk available commands with description :                                                             
+
+- `version` : Print version 
+- `storeconfig` : Store the static traefik configuration into a Key-value stores. Please refer to the [Store Træfɪk configuration](/user-guide/kv-config/#store-trfk-configuration) section to get documentation on it.
+
+Each command may have related flags. 
+All those related flags will be displayed with :
+
+```bash
+$ traefik [command] --help
+```
+
+Note that each command is described at the beginning of the help section:
+
+```bash
+$ traefik --help

+# Benchmarks
+
+## Configuration
+
+I would like to thanks [vincentbernat](https://github.com/vincentbernat) from [exoscale.ch](https://www.exoscale.ch) who kindly provided the infrastructure needed for the benchmarks.
+
+I used 4 VMs for the tests with the following configuration:
+
+- 32 GB RAM
+- 8 CPU Cores
+- 10 GB SSD
+- Ubuntu 14.04 LTS 64-bit
+
+## Setup
+
+1. One VM used to launch the benchmarking tool [wrk](https://github.com/wg/wrk)
+2. One VM for traefik (v1.0.0-beta.416) / nginx (v1.4.6)
+3. Two VMs for 2 backend servers in go [whoami](https://github.com/emilevauge/whoamI/)
+
+Each VM has been tuned using the following limits:
+

+
+## Conclusion
+
+Traefik is obviously slower than Nginx, but not so much: Traefik can serve 28392 requests/sec and Nginx 33591 requests/sec which gives a ratio of 85%.
+Not bad for young project :) !
+
+Some areas of possible improvements:
+
+- Use [GO_REUSEPORT](https://github.com/kavu/go_reuseport) listener
+- Run a separate server instance per CPU core with `GOMAXPROCS=1` (it appears during benchmarks that there is a lot more context switches with traefik than with nginx)

-# Building and Testing
-
-Compile and Test Your Own Traefik!
-{: .subtitle }
-
-So you want to build your own Traefik binary from the sources?
-Let's see how.
-
-## Building
-
-You need either [Docker](https://github.com/docker/docker) and `make` (Method 1), or `go` (Method 2) in order to build Traefik.
-For changes to its dependencies, the `dep` dependency management tool is required.
-
-### Method 1: Using `Docker` and `Makefile`
-
-Run make with the `binary` target.
-This will create binaries for the Linux platform in the `dist` folder.
-
-```bash
-$ make binary
-docker build -t traefik-webui -f webui/Dockerfile webui
-Sending build context to Docker daemon  2.686MB
-Step 1/11 : FROM node:8.15.0
- ---> 1f6c34f7921c
-[...]
-Successfully built ce4ff439c06a
-Successfully tagged traefik-webui:latest
-[...]
-docker build  -t "traefik-dev:4475--feature-documentation" -f build.Dockerfile .
-Sending build context to Docker daemon    279MB
-Step 1/10 : FROM golang:1.13-alpine
- ---> f4bfb3d22bda
-[...]
-Successfully built 5c3c1a911277
-Successfully tagged traefik-dev:4475--feature-documentation
-docker run  -e "TEST_CONTAINER=1" -v "/var/run/docker.sock:/var/run/docker.sock" -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -e VERBOSE -e VERSION -e CODENAME -e TESTDIRS -e CI -e CONTAINER=DOCKER		 -v "/home/ldez/sources/go/src/github.com/containous/traefik/"dist":/go/src/github.com/containous/traefik/"dist"" "traefik-dev:4475--feature-documentation" ./script/make.sh generate binary
----> Making bundle: generate (in .)
-removed 'autogen/genstatic/gen.go'
-
----> Making bundle: binary (in .)
-
-$ ls dist/
-traefik*
-```
-
-The following targets can be executed outside Docker by setting the variable `PRE_TARGET` to an empty string (we don't recommend that):
-
-- `test-unit`
-- `test-integration`
-- `validate`
-- `binary` (the webUI is still generated by using Docker)
-
-ex:
-
-```bash
-PRE_TARGET= make test-unit
-```
-
-### Method 2: Using `go`
-
-Requirements:
-
-- `go` v1.13+
-- environment variable `GO111MODULE=on`
-
-!!! tip "Source Directory"
-
-    It is recommended that you clone Traefik into the `~/go/src/github.com/containous/traefik` directory.
-    This is the official golang workspace hierarchy that will allow dependencies to be properly resolved.
-
-!!! note "Environment"
-
-    Set your `GOPATH` and `PATH` variable to be set to `~/go` via:
-
-    ```bash
-    export GOPATH=~/go
-    export PATH=$PATH:$GOPATH/bin
-    ```
-
-    For convenience, add `GOPATH` and `PATH` to your `.bashrc` or `.bash_profile`
-
-    Verify your environment is setup properly by running `$ go env`.
-    Depending on your OS and environment, you should see an output similar to:
-
-    ```bash
-    GOARCH="amd64"
-    GOBIN=""
-    GOEXE=""
-    GOHOSTARCH="amd64"
-    GOHOSTOS="linux"
-    GOOS="linux"
-    GOPATH="/home/<yourusername>/go"
-    GORACE=""
-    ## ... and the list goes on
-    ```
-
-#### Build Traefik
-
-Once you've set up your go environment and cloned the source repository, you can build Traefik.
-Beforehand, you need to get `go-bindata` (the first time) in order to be able to use the `go generate` command (which is part of the build process).
-
-```bash
-cd ~/go/src/github.com/containous/traefik
-
-# Get go-bindata. (Important: the ellipses are required.)
-GO111MODULE=off go get github.com/containous/go-bindata/...
-
-# Let's build
-
-# generate
-# (required to merge non-code components into the final binary, such as the web dashboard and the provider's templates)
-go generate
-
-# Standard go build
-go build ./cmd/traefik
-```
-
-You will find the Traefik executable (`traefik`) in the `~/go/src/github.com/containous/traefik` directory.
-
-### Updating the templates
-
-If you happen to update the provider's templates (located in `/templates`), you must run `go generate` to update the `autogen` package.
-
-## Testing
-
-### Method 1: `Docker` and `make`
-
-Run unit tests using the `test-unit` target.
-Run integration tests using the `test-integration` target.
-Run all tests (unit and integration) using the `test` target.
-
-```bash
-$ make test-unit
-docker build -t "traefik-dev:your-feature-branch" -f build.Dockerfile .
-# […]
-docker run --rm -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/user/go/src/github/containous/traefik/dist:/go/src/github.com/containous/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate test-unit
----> Making bundle: generate (in .)
-removed 'gen.go'
-
----> Making bundle: test-unit (in .)
-+ go test -cover -coverprofile=cover.out .
-ok      github.com/containous/traefik   0.005s  coverage: 4.1% of statements
-
-Test success
-```
-
-For development purposes, you can specify which tests to run by using (only works the `test-integration` target):
-
-```bash
-# Run every tests in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite" make test-integration
-
-# Run the test "MyTest" in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.MyTest" make test-integration
-
-# Run every tests starting with "My", in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.My" make test-integration
-
-# Run every tests ending with "Test", in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.*Test" make test-integration
-```
-
-More: https://labix.org/gocheck
-
-### Method 2: `go`
-
-Unit tests can be run from the cloned directory using `$ go test ./...` which should return `ok`, similar to:
-
-```test
-ok      _/home/user/go/src/github/containous/traefik    0.004s
-```
-
-Integration tests must be run from the `integration/` directory and require the `-integration` switch: `$ cd integration && go test -integration ./...`.
