Yes! I've confirmed that!
With TCP_NODELAY Cygwin and Linux times are similar.

One computer with dual boot, Linux in one partition and Windows with
Cygwin installed on another partition.
Boot on Linux compile echo_server.c, run it and it will listen on tcp
port 12345

Hello again,
as promised attached you will find a very simplistic non-blocking
echo server that compiles on Linux and Cygwin.
The main objective is that you compile it and run on both environments.
Of course that the same hardware is recommended in order to compare
the results in a more accu

Hello,
according to the mailing list archives it seems that I'm not the only
