Firefox startup impacted by distributed.net client

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
