>performance improved noticeably if I _decreased_ the number of buffers

The slow file system in most cases takes longer to search through its
buffers than to just re-fetch the block from the drive (depending on
how many buffers you have) so in many cases the fewer the better, and
in ALL cases, there's a point where you slow yourself down as you add
buffers.

Fixed in the rumored Fast Filesystem.
