The current server rpc tcp code attempts to predict how much writeable socket space will be available to a given RPC call before accepting it for processing. On a 40GigE network, we've found this throttles individual clients long before the network or disk is saturated. The server may handle more clients easily, but the bandwidth of individual clients is still artificially limited. Instead of trying (and failing) to predict how much writeable socket space will be available to the RPC call, just fall back to the simple model of deferring processing until the socket is uncongested. This may increase the risk of fast clients starving slower clients; in such cases, the previous patch allows setting a hard per-connection limit.
