On the same test postgresql is indeed faster, I haven't finished
benchmarking it yet though.

Kris, I'm interested at postgresql benchmarking at two-xeon-quad-core
server with 3WARE RAID adapter. Can you give me some tips?
Thank you.

Well I'm using sysbench and the collection of patches in my
kris-contention p4 branch. Sorry, I don't have an extracted patch set
available for you to try, but we're hoping to get the most important
patches into 7.0 within a week or two.

On the pgsql side, disable the update_process_titles option (or
whatever it is called), because this has a 33% performance overhead
for me. Also if you're testing over localhost, use a unix socket

As for me, I don't like testing with local clients.

If that's not the target workload you're trying to model, that's quite
reasonable. For me the only reason I have been using localhost
exclusively is because the test machines are currently only connected
by 100baseTX ethernet, which is not good enough for achieving high
query loads.
