Hello, Ian. You wrote 17 августа 2012 г., 18:56:33: IL> That result actually matches my expectation... it fixed only a part of IL> your problem. I was (partly) wrong :( Under ``really high'' load (4MiB/s up/down load in same time) userland freezes again. Unfortunately, it is difficult to repeat such load on request in y case, so I don't have KTR of scheduling in such case, but here is one thing I notice: when load is lower (like 2MiB/s both ways) ng_queue consume only 4-5% of CPU. And before freeze "top" shows ng_queue consumes about 60% of CPU. It is strange, as traffic goes up only at x2 rate... -- // Black Lion AKA Lev Serebryakov <lev_at_FreeBSD.org>Received on Sat Aug 18 2012 - 17:23:37 UTC
