Default PostgreSQL Performance issues - 07-13-2004 , 03:54 AM






Good day,

I hope you guys can help me, I went through the archives and spend some time
Googling, and I think my biggest problem is not really understanding all the
terms.
I would love some help on performance tuning our PG box, some of our queries
takes a very long time to complete.

My request is maybe more one of looking for a nice profiling system that can
eg. Graph available buffers vs used buffers, same with memory etc etc, to
try and find the bottleneck in our system and also for pro-active upgrades
where needed.

I will gladly post our conf files if that might help.

Many thanks in advance.

Regards
Werner vd Merwe

Have you checked to see if the speed of the slow running queries can be
improved by rewriting the SQL? If your problem is poorly written queries,
then analyzing buffers and memory isn't going to help.
