I agree.  I was just showing how much disk choice impacted worldstone
performance.  Much more so than overclocking did.  I got a big win
also from mounting /usr/obj async and /usr/src noatime,noasync.  I
suspect that I'd have gotten a win from having /usr/obj and /usr/src
on different spindles maybe with ccd in the mix.
