One thing we should have by then is a decent idea of what = to select as default burst duration. But since this is not urgent, there is= no objective need to expedite this testing...

I want to= clean up things by removing the old burst scaling mode, but want/need conf= irmation that the new duration based method actually works as intended. (My= next step then will be putting the axe on the quantum scaling, where I pla= n to use exactly the same size as for burst, on the theory that worst case = we can only push bust bytes to the NIC and should try to service the other = priority tiers at latest on the next HTB execution iteration). > >> > >> Best Regards > >> Sebastian > > > > I meant to get time to fiddle with it yesterday and I didn't.

Would be interested to hear = whether that does "the right thing" with your APU or on other's devices? Th= e key variable is TARGET_BURST_DUR_MS in defaults.sh. Let me know how this = performs for you (or whether there are bugs). As Toke proposed elsewhere I = will try to streamline that branch to only configure burst size by duration= so expect some changes in organization, but it should keep functional. > >>>> > >>>> Best Regards > >>>> Sebastian > >>>> > >>>>> On Sep 11, 2018, at 10:20, Dave Taht wrote: > >>>>> > >>>>> What I "fixed" was on the apu2 with the burst/cburst change, I went > >>>>> from completely bottlenecked on one softirq to having 3 eat cpu, an= d > >>>>> from 400mbps to 900mbps.
