	Oops, sorry, it looks I copy and pasted the wrong line from my .bash_history… the following should work:

git clone https://github.com/tohojo/netperf-wrapper

also note Dave’s mail where he recommends:
sudo apt-get install fping python-qt4 python-matplotlib

to get more of the requirements for netperf-wrapper installed,  please run this after coning the netperf-wrapper repository.

Thanks a lot…

	Sebastian

I assume it might take a bit trying to figure out all the required packets installed, but it should be reasonably quick to get this up and running… Just give it a try and let me know if/where you get stuck

Shaping at the rates you are interested in probably will take 100% CPU of the router, so there is no slack for running net server and netperf instances at the same time. Also I would recommend to use netperf-wrapper (https://github.com/tohojo/netperf-wrapper) instead of netperfrunner.sh as it allows so much nicer visualization of the queueing over time. netperfrunner.sh is great tool for quick testing and figuring out link capacities and worst case latency under load increase (LULI), but for more thorough comparisons it ain’t made. Netperf-wrapper will run under linux and macosx natively, but will also run (well enough) in a linux virtual machine on a windows box.
