You think so?

10MB/sec in bonnie++ seems pretty fast to me.  Of course, I don't get paid
to spend time finding the best combinations of hardware.  It certainly
outperforms the Gateway 2000 desktop that I have.  (It *didn't* outperform
it with the old drive.)  What kinds of numbers do you get with bonnie++?
What kind of hardware?  Are you using softdeps or LFS?

Maybe now that the drive problems are fixed, it would help to twiddle some
BIOS options (I turned several features on/off to see if they impacted
performance on the old drive), or turn on softdeps or the like.  But for
the moment, I don't have time to mess with that, and the speed is
absolutely luxurious compared to before.
