Please take note with using iperf that you'll want to make sure the appropriate TCP Window Size has been negotiated. We recently did some testing with systems that had decided to pick less than optimal window sizes and in turn had to manually set the size within iperf options.
Indeed this is true. Also, if you use one of the Internet2 network test web100-enabled servers, you can try testing through a web browser. There's both NPAD and NDT on distributed on different nodes, although each has its own slightly different tests. It's also not a bad set of tools for support people wanting to troubleshoot bandwidth problems caused by duplex misconfigs.

Anyone have a good solution to get "accurate" speed results when testing at 10/100/1000 Ethernet speeds?
Do you have a server/software that customer can test too?
