Linux always worked best for us as well, was easy running a livecd with laptops. We found that two windows XP machines, same identical hardware and OS load yielded different registry settings (or lack thereof) for TCP Window setting.

True, we usually find Linux based machines work better running IPerf then Windows (at least out of the box) because of the TCP window size....well Windows XP at least, don't know about Vista or 7. Jason Biel wrote:
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.

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?
