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 still loaded, after turning on simple_qos.sh, set for ~85% of the rated up/down bandwidth... 4) then killing the load, and keeping simple_qos enabled. I export each detailed (you have to select it) .csv output from that benchmark to a file. I do it against a bidirectional 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. ) then starting the web tests 10-20 seconds later.

You can also run the rrul test (preferably for 5 minutes or more because this test idea KILLs web page load times) to get a heavier load and more graphs.
