I have an application that reads data from a socket. The data is perpetually written to the socket so I am fairly certain that it is the receive call that's causing the delays.

From timing debugging output, the recvfrom call returns after ~1ms. However, occasionally, there is a call that takes 10 ms. Is this a bug in select?


It's hard to be sure without some serious kernel-level investigation.

Is there a reason you just can't put the socket in non-blocking mode?
