>Question/Comment:
>When using iperf-1.7.0-win32.exe between two Windows XP boxes using the
following CLI parameters iperf reports a 4MB window, however an ethereal
packet capture shows the window size to be 64KB:
>
>server side - iperf -s -w 4m
>client side - iperf -c server.ip.address -w 4m -i 1
>
>Note that the throughput on the test is consistent with a 64KB window.
