Just saw this (libevent2 performance linux vs. windows).
http://www.mail-archive.com/[email protected]/msg01730.html
Linux (virtual machine) : 1220 Mb/s (cf. 1.45 Gb/s using select directly)
Windows (select) : 96 Mb/s (cf. 100 Mb/s using select directly)
Windows (IOCP) : 125 Mb/s
Libevent2 can use iocps because if offers a special file handle
abstraction which can take advantage of iocps.
However, barring some phenomenal shortcoming/bug in libevent2, it seems
that windows throughput doesn't improve that much with iocps.
Of course, this benchmark *probably* uses few fd's, so it doesn't actually
test scalability of select vs. iocps, but then, it seems it's entirely not
worth it to support windows, at leatsf or high-throughput applications.
Just looked interesting...
