Original message, from ten months ago: http://lists.freebsd.org/pipermail/freebsd-hackers/2010-May/031915.html Briefly, running the distributed.net client on my FreeBSD 8.0 box made Firefox take forever to start up (90 seconds vs. 2 seconds). The distributed.net client is essentially 100% CPU bound, with occasional file I/O and even more occasional socket I/O, running at nice 20. The problem has persisted since then. So I finally compiled up a kernel using SCHED_4BSD instead of SCHED_ULE. Problem fixed. It still doesn't give me a warm, fuzzy feeling about FreeBSD 8.0, since I still have the awful NFS client performance problem (though not as bad as before the Rick Macklem patch). -- George Mitchell
