Is it typical to ZFS to run over 100 kthreads? I see a lo= t of spa_*s in ps output. Yes, that's the Solaris default. It's starts eight spa_zio_issue and eight spa_zio_intr threads for each ZIO type and there are six of them, which gives 2*8*6=3D96 threads. We may want to reduce it for FreeBSD, but I see no reason doing so except for a nicer ps(1) output. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
