Vegas should not be reacting to the base delay, only to > jitter. The insanely high amount of TX_RETRY (13) on the first (nanostation) network might have had something to do with it. The debloated device (a wndr 5700) had TX_RETRY=4. It remains puzzling. I am doing a new build of openwrt for the nanostation net (incorporating babel-1.1 - thx!) But ran into problems elsewhere in getting a build done, so I'm a ways from being able to play with this comprehensibly. And I'd like to expose TX_RETRY to userspace at some point. And it would be cool to get more drivers - like the iwl-lagn - debloated. > > --Juliusz > > > > > _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat -- Dave Taht http://nex-6.taht.net
