How to test network performance?

[bozrdang]

I have upgraded most of my home network to Gigabit, but I'm having doubts that it's running right. Is there any software I can download to verify I'm getting the speed I should?

But what should it be?

Giga Byte, probably 200Mb/sec.

You can try iperf: http://dast.nlanr.net/Projects/Iperf/

I stick with version 1.7.

E.g. from a command prompt:

server: iperf -s
client: iperf -c server -l 64k -t 12 -i 3 -r

E.g. typical results for decent modern networking, without jumbo frames:

F:\tools\bench\iperf>iperf -c 192.168.0.168 -l 64k -t 12 -i 3 -r
