I have been collecting statistics on th= e behavior of the 3.7.5-2 version of cerowrt, and perhaps y'all out the= re can help. I've been doing four repeatable tests.

I feed the attached file into the chrome web page benchmark = and run it 4 times:

1) No other load on the system
2) while running a = single up and single down netperf stream to icei.org (on the east coast)
3) then while sti= ll loaded, after turning on simple_qos.sh, set for ~85% of the rated up/dow= n bandwidth...
4) then killing the load, and keeping simple_qos enabled.
I export each detailed (you have to select it) .csv output fro= m that benchmark to a file.

I do it against a bidi= rectional stream - one each of

netperf -l 6000 -4 -H icei.org -t TCP_MAERTS &
netperf -l 6000 -4 = -H icei.org -t TCP_STREAM= &

(if you have ipv6, more power to you, kill the -4. )=A0=

then starting the web tests 10-20 seconds later. It'= ;s interesting to watch cero's bandwidth graphs while doing this.

There are netperf servers setup on the east (icei.org) and west coast (snapon.lab.bufferb= loat.net) and a few other places. It would be sane to setup your own so= meplace you control (from netperf's svn compiled with --enable-demo), a= s it helps to have a shorter RTT to truly load up the link. You can also ru= n the rrul test (preferably for 5 minutes or more because this test idea KI= LLs web page load times) to get a heavier load and more graphs.=A0

If you are up to trying this test series, please let me= know, send along the details of your setup, and the 4 csv files, and perha= ps your data will show up in an upcoming paper.

The chrome web page benchmark can be had at:


And requires you fire off chrome with --enable-benchmar= king
