It is definitely using Cake as the shaper; in besteffort mode, but with nat and triple-isolation enabled I think. I'll run another test tomorrow with those disabled. > There's also a minor complication in that Cake and fq_codel behave > differently when handed superpackets.

Also would be nice to get a measure of the smoothness of the shaper; will see if I can't extract that from a pcap file or something... -Toke _______________________________________________ Cake mailing list Cake@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cake
