Just a data point, but on my Dual Xeon 2.4Gig machine with a 10k SCSI
drive I can do 4k inserts/second if I turn fsync off.  If you have a
battery-backed controller, you should be able to do the same.  (You will
not need to turn fsync off --- fsync will just be fast because of the
disk drive RAM).

Am I missing something?
