If I could get you to do a netperf-wrapper rrul_be test on the same link, I would believe you are getting a valid result. Remember that one machine running a test program may not be able to mess up the network, but most people/families/offices have way more people and way more machines. I have successfully got netperf-wrapper to build on OSX on macports, but not brew. Alternatively, load up the link with a bunch of netperfs, and while doing a ping. Since it is hard to get 250Mbit service, here's a rough equivalent of the rrul test aimed at multiple sites. ping 8.8.8.8 > ping.log & netperf -H netperf-eu.bufferbloat.net -l 300 -t TCP_MAERTS & netperf -H netperf-eu.bufferbloat.net -l 300 -t TCP_MAERTS & netperf -H netperf-west.bufferbloat.net -l 300 -t TCP_MAERTS & netperf -H netperf-east.bufferbloat.net -l 300 -t TCP_MAERTS & netperf -H netperf-eu.bufferbloat.net -l 300 -t TCP_STREAM & netperf -H netperf-eu.bufferbloat.net -l 300 -t TCP_STREAM & netperf -H netperf-west.bufferbloat.net -l 300 -t TCP_STREAM & netperf -H netperf-east.bufferbloat.net -l 300 -t TCP_STREAM & > -- > Mikael Abrahamsson email: swmike@swm.pp.se > _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat --=20 Dave T=C3=A4ht Open Networking needs **Open Source Hardware** https://plus.google.com/u/0/+EricRaymond/posts/JqxCe2pFr67
