Flamegraph analysis showed that the cork/uncork calls consume nearly a third of the CPU time spent in svc_tcp_sendto(). The other two consumers are mutex lock/unlock and svc_tcp_sendmsg(). Now that svc_tcp_sendto() coalesces RPC messages properly, there is no need to introduce artificial delays to prevent sending partial messages. After applying this change, I measured a 1.2K read IOPS increase for 8KB random I/O (several percent) on 56Gb IP over IB.
