Well, at least on my test machines running gnome-terminal, my pgbench
runs tend to get throttled by gnome-terminal's lousy performance to no
more than 300 tps or so.

By "tuning" fsync,
Not much we can do unless you give us more info about how you're testing
(pgbench setup), and what you've done with the parameters you listed
below. It would also be useful if you told us more about your drive
array than just "3Par". We need to know the RAID level, number/speed of
disks, whether
