IPERF to test throughput

Matthew Midgett

I haven't bought one yet so I am hoping that someone can run IPERF as the client and server not in duplex mode with the parallel thread option. Need to see how close to gigabit it can get.

Client

iperf -c IP_Address -P8 -t60

Server
iperf -s

You can run from bsd or linux to it if you don't have two to test with.
