I ask because we have a shipload of = costly iptables/tc filter stuff only happening in simple.qos (while rural_b= e will not use any DSCPs besides 0 the filters should still cost a bit CPU)= .

I still do not see any reason for precedence or diffserv8 to exist, and can barely cope with the idea of diffserv4. > > Best Regards > Sebastian > > >> On Dec 20, 2015, at 13:52 , Dave Taht wrote: >> >> the 200/20mbit tests I ran yesterday. >> >> http://snapon.cs.kau.se/~d/ptests/ >> _______________________________________________ >> Cake mailing list >> Cake@lists.bufferbloat.net >> https://lists.bufferbloat.net/listinfo/cake >
