So column 7 (ipv4) and column 8 (ipv6) are larger than col= umns 9 (ipv4) and 10 (ipv6) showing that dual egress instead of egress and = ingress effective upload increases by < 10 Mbps (while download and latency= stay unaffected). That is not bad, but also does not look like the IFB is = the cost driver in sqm-scripts, or does it? Also as a corollary of the data= I would say, my old interpretation that we hit a limit at ~70Mbps combined= traffic might not be correct in that ingress and egress might carry slight= ly different costs, but then thins difference is not going to make a wndr p= unch way above its weight=E2=80=A6 > > Best Regards > Sebastian > > > > > On Mar 23, 2015, at 17:09 , Sebastian Moeller wrote: > >> Hi Jonathan, >> >> On Mar 23, 2015, at 14:43 , Jonathan Morton wrot= e: >> >>> >>>> On 23 Mar, 2015, at 08:09, Sebastian Moeller wrote: >>>> >>>> It obviously degrade local performance of se00 and hence be not a true= solution unless one is happy to fully dedicate a box as shaper ;) >>> >>> Dedicating a box as a router/shaper isn=E2=80=99t so much of a problem,= but shaping traffic between wired and wireless - and sharing the incoming = WAN bandwidth between them, too - is. outer >> >> Exactly the sentiment I had, but less terse and actually understan= dable ;) >> >>> It=E2=80=99s a valid test, though, for this particular purpose. >> >> Once I get around to test it, I should b able to share some number= s=E2=80=A6 >> >> Best Regards >> Sebastian >> >>> >>> - Jonathan Morton >>> >> >> _______________________________________________ >> Cerowrt-devel mailing list >> Cerowrt-devel@lists.bufferbloat.net >> https://lists.bufferbloat.net/listinfo/cerowrt-devel > > > _______________________________________________ > Cerowrt-devel mailing list > Cerowrt-devel@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/cerowrt-devel > --=20 Dave T=C3=A4ht Let's make wifi fast, less jittery and reliable again! https://plus.google.com/u/0/107942175615993706558/posts/TVX3o84jjmb
