I can recommend iperf too.

Make sure you use the same iperf version everywhere.

With iperf you can measure TCP throughpuh with one or more threads, and also
UDP throughput.. which also gives you packet loss statistics, which might be
good to know to figure out there performance problems..

(TCP automatically corrects/retransmits error packets so with TCP you just
see poor performance in case of network/driver problems. With UDP you can 
get the actual statistics about packets transferred and dropped and figure
out the reasons).
