[PERFORM] Looking for hw suggestions for high concurrency OLTP app

2006-12-11 Thread Cosimo Streppone
Hi all, I'd like to get suggestions from all you out there for a new Postgresql server that will replace an existing one. My performance analysis shows very *low* iowaits, and very high loads at times of peak system activity. The average concurrent processes number is 3/4, with peaks of 10/15.

The Sun X4600 is very good for this, the V40z is actually EOL so I'd stay away from it. You can currently do 8 dual core CPUs with the X4600 and 128GB of RAM and soon you should be able to do 8 quad core CPUs and 256GB of RAM. - Luke On 12/11/06 8:26 AM, Cosimo Streppone [EMAIL PROTECTED]
