I dont for the life of me pretend to know how it works having never heard of this before.
But a quick google lead me to a gui for it: http://code.google.com/p/xjperf/

You need a version of java installed on both machines, then just run the bat file. Set one end to client and the other to server, pop the ip address of the server into the client and away you go 
Try download this bat file: https://rapidshare.com/files/2552346570/jperf.bat
The original .bat file is designed with a different location for Java in mind, I think for windows XP, for windows vista and windows 7 the .bat I linked to (uploaded myself) should work fine.
When run it should open up a cmd prompt for a split second and then close, then a few seconds later the java interface for iperf will open.
It is quite simple to use but the results are not always that easy to interperate. For example I'm using it for a project and annoyingly when doing 2-way tests the bandwidth in one direction over my LAN is different from the same route but with data going the other way.

you need to add jperf into the system PATH environment variable. Just start typing environment in the win7 search box, click on the environment variables button at the bottom, go to the path field under system variables and at the end of the line add a semi colon followed by the the path to your Java runtime folder, for me it's
Do this on both computers and the .bat file should launch jperf.
then set one computer as server and press run, then go to your client and run that to the server ip address. On a gigabit network you'll want to increase the window size up from 8 to 64 (this is something windows does itself on file transfers, so it's not cheating)
You'll probably also want to change the units to Mbits in the drop down box.
