If you put client/server on the same machine, then we don't know how the
CPU is splitted. Can you take a look at the approximate number by
observing the task manager data while running?
If communication code is the suspect, can we measure the difference if we
disable the redefinition of recv()/send() etc in port/win32.h (may require
change related code a little bit as well). In this way, the socket will
not be able to pickup signals, but let see if there is any performance
difference first.
