Re: PERFORMANCE

hi,

I forgot to say that you should consult the posgtres admin's manual.

 + Use explain to figure out which query should be speeded up.
 + Consider using seperate disks for logging, for database cluster and
    for indexes.
 + vacuum db frequently
 + revise indices (insufficient, unused, unneccessary, too many), etc.

ps: stick to postgres, though it may be a love of war somtimes.

Hi,

I think there are many people who can help you, but you have to share
more details about your configuration (for example sw, versions, etc)
scheme information can be helpful quite helpful as well.

how did you config your database? (show us a postgres.conf)

So, it's still your turn.

Subject: [PHP] PERFORMANCE


| Hello,
|
| I´m new on the list and I´ve been using postgres on a production
| environment for 3 months.  My team and I have developed a system for a
| Hospital in which we work with php-postgres-linux.  In the begining
| everything was fine.  As soon as the tables grew larger, we´ve begun to
| experience an enormous performance fall.  By now, the system is almost
| crawling.  We´ve already made all possible changes on hardware, which is a
| COMPAQ ML370, scsi, with 2 PIII 800 and 768 MB RAM.  The only test we will
| still do is to change the scsi controller for an ultra 160.  On the other
| hand, searching the archives of this list, I´ve collected many complaints
| about degradation of performance of insert/update, as tables are
| populated.  My question is:
|
| "IS THERE ANYONE THAT CANT GIVE US SOME HOPE TO PERSIST ON POSTGRES OR IS
| THIS A LOST BATLE?"
|
| If so, we need some advice to change this situation, instead of changing
| database or bying a supercomputer?
|
| Thanks
|
| Paulo
