+# 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:1.5
+ ---> 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` v1.5+ (1.7 is acceptable)
+- You need to set `$ export GO15VENDOREXPERIMENT=1` environment variable if you are using go v1.5 (it is already enabled in 1.6+)
+- 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` 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
+# 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
+```
+
+### 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

-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), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher v2](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.

-:warning: Please be aware that the old configurations for Traefik v1.x are NOT compatible with the v2.x config as of now. If you're running v2, please ensure you are using a [v2 configuration](https://doc.traefik.io/traefik/).
+Træfɪk 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), 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.
+
+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 = "Host: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 is 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 if condition matches, CB enters Tripped state, where it responds with predefines code or redirects to another frontend.
+Once Tripped timer expires, CB enters Recovering state and resets all stats.
+In case if 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
+```
+## 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"

+- 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 begining. 
+- 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 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 overrides 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 begining of the help section:
+
+```bash

+# 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:
+
+```bash
+sysctl -w fs.file-max="9999999"
+sysctl -w fs.nr_open="9999999"
+sysctl -w net.core.netdev_max_backlog="4096"
+sysctl -w net.core.rmem_max="16777216"
+sysctl -w net.core.somaxconn="65535"
+sysctl -w net.core.wmem_max="16777216"
+sysctl -w net.ipv4.ip_local_port_range="1025       65535"
+sysctl -w net.ipv4.tcp_fin_timeout="30"
+sysctl -w net.ipv4.tcp_keepalive_time="30"
+sysctl -w net.ipv4.tcp_max_syn_backlog="20480"
+sysctl -w net.ipv4.tcp_max_tw_buckets="400000"
+sysctl -w net.ipv4.tcp_no_metrics_save="1"
+sysctl -w net.ipv4.tcp_syn_retries="2"
+sysctl -w net.ipv4.tcp_synack_retries="2"
+sysctl -w net.ipv4.tcp_tw_recycle="1"
+sysctl -w net.ipv4.tcp_tw_reuse="1"
+sysctl -w vm.min_free_kbytes="65536"
+sysctl -w vm.overcommit_memory="1"
+ulimit -n 9999999
+```
+
+### Nginx
+
+Here is the config Nginx file use `/etc/nginx/nginx.conf`:
+
+```
+user www-data;
+worker_processes auto;
+worker_rlimit_nofile 200000;
+pid /var/run/nginx.pid;
+
+events {
+    worker_connections 10000;
+    use epoll;
+    multi_accept on;
+}
+
+http {
+    sendfile on;
+    tcp_nopush on;
+    tcp_nodelay on;
+    keepalive_timeout 300;
+    keepalive_requests 10000;
+    types_hash_max_size 2048;
+
+    open_file_cache max=200000 inactive=300s; 
+    open_file_cache_valid 300s; 
+    open_file_cache_min_uses 2;
+    open_file_cache_errors on;
+
+    server_tokens off;
+    dav_methods off;
+
+    include /etc/nginx/mime.types;
+    default_type application/octet-stream;
+
+    access_log /var/log/nginx/access.log combined;
+    error_log /var/log/nginx/error.log warn;
+
+    gzip off;
+    gzip_vary off;
+
+    include /etc/nginx/conf.d/*.conf;
+    include /etc/nginx/sites-enabled/*.conf;
+}
+```
+
+Here is the Nginx vhost file used:
+
+```
+upstream whoami {
+    server IP-whoami1:80;
+    server IP-whoami2:80;
+    keepalive 300;
+}
+
+server {
+    listen 8001;
+    server_name test.traefik;
+    access_log off;
+    error_log /dev/null crit;
+    if ($host != "test.traefik") {
+        return 404;
+    }
+    location / {
+        proxy_pass http://whoami;
+        proxy_http_version 1.1;
+        proxy_set_header Connection "";
+	proxy_set_header  X-Forwarded-Host $host;
+    }
+}
+```
+
+### Traefik
+
+Here is the `traefik.toml` file used:
+
+```
+MaxIdleConnsPerHost = 100000
+defaultEntryPoints = ["http"]
+
+[entryPoints]
+  [entryPoints.http]
+  address = ":8000"
+
+[file]
+[backends]
+  [backends.backend1]
+    [backends.backend1.servers.server1]
+    url = "http://IP-whoami1:80"
+    weight = 1
+    [backends.backend1.servers.server2]
+    url = "http://IP-whoami2:80"
+    weight = 1
+
+[frontends]
+  [frontends.frontend1]
+  backend = "backend1"
+    [frontends.frontend1.routes.test_1]
+    rule = "Host: test.traefik"
+```

+
+## 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)
