Re: Setting -w on v1.6 Win32 of Iperf
Iperf checks the Window size set and if it's different from the requested
window size, it prints out a warning. (For example, Linux generally
allocates twice the Window size requested). So, I guess this must be
something peculiar to Win2K that the OS reports the Window size is some
value, but the value actually set is different.
If you're sure no warning is printed out, it's a Win2K problem.
