I want to c= lean up things by removing the old burst scaling mode, but want/need confir= mation that the new duration based method actually works as intended. (My n= ext step then will be putting the axe on the quantum scaling, where I plan = 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 pr= iority 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 wh= ether that does "the right thing" with your APU or on other's devices? The = key variable is TARGET_BURST_DUR_MS in defaults.sh. Let me know how this pe= rforms for you (or whether there are bugs). As Toke proposed elsewhere I wi= ll try to streamline that branch to only configure burst size by duration s= o 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, and > >>> from 400mbps to 900mbps.
