Have you tried 8 stable?
The box I tried SCHED_4BSD on was running 8.2_PRERELEASE, which still
had the problem described. Has the scheduler changed significantly
between 8.2_PRERELEASE and stable? -- George Mitchell

Original message, from ten months ago:

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
