From 79ffef1fe213851f44bfccf037170a140e929f85 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 27 Feb 2013 07:05:03 +0000 Subject: tcp: avoid wakeups for pure ACK TCP prequeue mechanism purpose is to let incoming packets being processed by the thread currently blocked in tcp_recvmsg(), instead of behalf of the softirq handler, to better adapt flow control on receiver host capacity to schedule the consumer. But in typical request/answer workloads, we send request, then block to receive the answer. And before the actual answer, TCP stack receives the ACK packets acknowledging the request. Processing pure ACK on behalf of the thread blocked in tcp_recvmsg() is a waste of resources, as thread has to immediately sleep again because it got no payload. This patch avoids the extra context switches and scheduler overhead.
