I didn't see one go by yet... Could be sitting in the queue.
If it's not arrived by now - EXPLAIN ANALYZE doesn't tell me
anything :)
Let us know if changing the fsync setting helps. Hopefully that's all
the problem is.
fsync's already off - yes a bit scary, but our I/O is only about
500KB/sec writing.. the whole db fits in RAM / kernel disk cache, and
I'd rather have performance than security at this exact moment..
Multi-Opteron was the other thing we considered but decided to give
'Big Iron' UNIX a whirl...
It still might be a good choice, if it's a simple misconfiguration
issue.
But man, those new multiple core opterons can make some impressive
machines for very little money.
So I see - we could buy two quad-opterons for the cost of renting this
pSeries for a month....
I don't know about the pSeries, but I had a client the other week with
the same usage pattern. They made the switch from a quad Xeon to dual
(+dual-core) Opteron and were extremely impressed.
I can probably put you in touch with their sysadmin - contact me
off-list if you'd like that.
