Hello,
I seem to have reached some type of maximum bandwidth with iperf 1.7.0. 
At the default TCP window size, I would generally get a b/w in the 
920's. As I stepped up the window size, I started getting a bit higher 
readings until everything seemed to max out at 941 Mb/s. Now, with a 
window of 256K and larger, I get 941 Mb/s every time -- almost like it 
is getting cut off at that point. I guess it could also be the switch 
(Foundry FI1500), but does anyone know of a possible limit here to 
iperf? Thanks,
-Cameron
