whatever you are running

what are you trying to test? usually you don't get much value in testing a 
when you go through 
a router that is a bottleneck. so testing from one machine on your network to 
another machine on your network isn't going to find anything

It boils down to

1. do a latency test with no other load ( ping works )

2. start a large upload and see what happens to latency during the upload

3. start a large download and see what happens to latency during the download

4. start an upload and download and see what happens to latency.

the netperf test does this by having you run a netperf server on one system (on 
the other side of the router that is your bottleneck), then run the test from 
a machne on your network, and it does allt he steps above for you.
