Hi, 
I am using a Dell poweredge 2400 server , P3, 256 Mb, 
82546 EB GBE card, E1000. 
I tried working with various very high window options
(w 32M etc)  in iPERF ...but to no awail!! The
throughput saturates  at around 140 Mb/s  even for
jumbo frames.:(   
I will revert to my older kernels and see if I get
somewhere, ...pl keep the comments comming!
