* 8.3.1 vs 8.2.X on HP-UX PA-RISC 11.11/11.23

We run GCC-compiled postgresql on a number
of HP-UX and Linux boxes.

Our measurements to date show 8.3.1
performance to be about 30% *worse*
than 8.2 on HP-UX for the same "drink the firehose"
insert/update/delete benchmarks.  Linux
performance is fine.  

Tweaking the new 8.3.1 synchronous_commit
and bg writer delays that *should* speed
things up actually makes them a bit worse,
again only on HP-UX PA-RISK 11.11 and 11.23.

Right now it's 32 bit, both for 8.2 and 8.3.  

Any hints?

Are you using the same locales for both?

Yes.  Locale is 'C' for both 8.3.1 and 8.2.1.
