[RndTbl] NIC performance with iperf

[Colin Stanners]

I installed a cheap GigE switch for a customer using 2006-era P4 Dell 
desktops,
running XP with cheap Broadcom GigE NICs. Constant 600-700mbit for file 
transfers.
CPU I think was ~30%, but that may have included the AV scanning the file.

I assumed Iperf is developed/optimized natively under *NIX and the Windows
version is compiled under Cygwin, do you have any indication that it's 
optimized?
