The old system has a 80GB, 5200rpm ATA , the new system a 120GB, 7200rpm ATA. The new system should at least not be slower. Also, on the new system I have a separate partition for the database.

If I run a Vacuum or a SELECT COUNT(*) on a larger table (2-6 million records) the systems responds very slow, the screen almost freezes.

Thanks

Hi,
I just installed pg 7.4.1 on a new system P4, 3.2Gh HT, 1GB Mem, RH9
and discovered that some of the processes have become extremely
slow. Mainly I am talking about a SELECT COUNT(*) or VACUUM.

Before running the same database on a P4. 2Ghz 412MB mem, I got the
job done in some cases half the time.

The weird thing however is, that normal inserts seem to be much faster
on the new system and I am wondering if it is Postgres or HW related.

Does anyone has an advise ?



What kind of disk hardware is on the two systems?
