Thread: Configuration for my server
Hello... Here is my server hardware configuration: 2x Xeon 1MB Cache 3GHZ + 4GB RAM basicly it one of Intel Server SR2400 configuration ;) with two Seagate discs 146GB 15k connected with RAID1. I have installed PSQL ver. 8.0 and try to find best configuration. Nowadys we have about 300 clients connected to mysql server (we plan to switch to postgresql) but in the future there will be even 1 thousand clients. Can anyone please help me what should I change in postgresql.conf to achieve very good performance ;) Thx Marcin
I think you should also state what operating system you are using.

Secondly, if your database is going to handle a fair bit of writing then make sure your RAID controller has battery backed cache on it. With 300 to 1000 users, and 5% or so writing, this isn't an option, it's a requirement. :) On a fast machine with lots of memory, it often pays to drop random_page_cost to 1.2 to 1.4 or so.
