It looks like it does support threading; but not what you think. All server I/O is processed by 1 thread, and the other thread is VAC?. >Please, please, please work on server performance.

Source on windows does not use gettimeofday; that is *NIX only. System calls, generally, are expensive. Windows 2003 uses PIT/ACPI to drive clocks, which effects things like sleep(). I think Sleep() on windows is expensive to call because calling Sleep() reads the PIT/ACPI, which requires an ioport read, which is very expensive.. I'm not sure on this; but that would explain why I see so much jitter from sleep() calls Windows 2008 uses HPET to service interrupts and timing, and it's faster than the former.
