I will argue that that would give a much better estimate as to how much data was really outstanding on the wire. > > Don't go telling Dave about that, he wants me to put too much into netperf > as it is!-) Please release 2.7 soonest so we can get it into openwrt chaos calmer. Then we can discuss new features, like the UDPLITE stuff and this. :) That said, I would like try a comparison test against rrul results taken with and without the tcp_notsent_lowat option in netperf when I get back from vacation next week. My guess is that it won't affect the stats we get currently much (might hurt as netperf will run more often), but MIGHT reduce the tail burst problem we see fairly often at the conclusion of the test > > rick > -- Dave Täht Open Networking needs **Open Source Hardware** https://plus.google.com/u/0/+EricRaymond/posts/JqxCe2pFr67 _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
