You are welcome, but does this actually work for you? I want to = clean up things by removing the old burst scaling mode, but want/need = confirmation 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 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 priority tiers at latest on the next HTB = execution iteration).

Would be interested to = hear whether 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 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. >>=20 >> Best Regards >> Sebastian >>=20 >>> On Sep 11, 2018, at 10:20, Dave Taht wrote: >>>=20 >>> 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.
