Please cc the list so others can help.
How large is the database? What indexes are on the tables you're inserting
into? What speed is the drive?
Since it's a single SCSI drive I'm assuming it's only 10k RPM, which means the
theoretical maximum you can hit is 160 transfers per second. At 40 inse

If you put data & xlog on the same array, put them on seperate

Well they don't necessarily have the same value!
It's a dictionary with cross-referenced words, e.g. 'bring' and
'brought' are both headwords in the dictionary, but 'brought' is
cross-referenced to 'bring'. So, the table stores the information (using
integer id's rather than words) that
