Description

io_uring has an IORING_RECVSEND_POLL_FIRST which will increase the performance of read/recv/recvmsg/recvfrom calls if no data is present in the socket at the time we submit a read.

This works by going directly into poll, bypassing the initial attempt to recv/recvmsg.

Given that our sockets are often very low traffic and work in a request/response fashion, this might be worth a shot.
