I would certainly like more folk to analyse fq_codel, particularly in the context of TCP mice and what we call ANTs these days. It seems to be really excellent, but I too haven't had much time to look at it, yet. It certainly does an even better job than codel of allowing sparse streams through in my own testing, and I run it by default on my laptops, wireless gear, routers and desktop at present. Under heavy load things like cerowrt and ssh and other stuff like mosh, remain incredibly responsive. With ponies that good, there has got to be some manure somewhere. > =A0- Jonathan Morton > > _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat --=20 Dave T=E4ht SKYPE: davetaht US Tel: 1-239-829-5608 http://www.bufferbloat.net
