7.3.2 : poor performance for me :-(

From

hi !

I used postgres 7.2 before on a server A.

Accesses are made by another machine (B) via PHP


Client on server B is from a 7.0 release.

when it was a 7.2 on the DB machine, everything was ok.

Now, with a 7.3.2, access are very slow (updates and select).

Do you think it is possible it is because I use 7.0 libs with PHP on server B
??

Thanks for your help !

Well, I answer myself to my mprevious message !

It "seems" it's better with a 7.3.2 client.

If someone has a clue to optimize performance, thanks !


Our DB size id about 340 Mo

Largest table has 400K tuples.

We often have 3 or 4 updates in the same time on this tables, and selects in
the same time.

It runs on a P4 1.8G, with 1Go RAM, SCSI Disks

Postgres options are :

 -B60564 -N255 -S131072

seqscan is off

Wal_buffers = 2048

We do a vaccum every 6 hours and a vaccum -f once or twice a week.
