Hi,

I am running iperf on both FreeBSD4.7 and Redhat 7.3.

I think i cannot get  max throughput out of 1Gbps ethernet adapter because the 
window size max's out at 264Kbytes. I need a larget window size to get full 
bandwidth out of this adapter.

What is the configuration change required for each OS ?

thanks,
- Nirav
