Hello

Sorry, this may be a bit off topic but I am sure there are many people on
this list who have experience of this.

I am doing some performance testing using iperf between 2 Windows 2008
servers with a latency of around 80ms and a minimum available bandwidth of
200Mbps.

According to the following URL
http://www.switch.ch/network/tools/tcp_throughput/ the optimal TCP window
size should be around 2MB

required tcp buffer to reach 200 Mbps with RTT of 80.0 ms >= *2048.0 KByte*

What throughput should I expect to see with this setting? Should it be
reaching 200Mbps or what would be a more realistic value?

Many Thanks
Ian Blaney
