System Requirement - Mailing list pgsql-performance

Hi All,

We are looking to upgrade to 8.0 from 7.3.2 on production server. The current production system we are using is

----------------------------------------

2 x 2.4 Ghz Intel Xeon CPU with HT(4 virtual CPUs)

RAM - 1GB

HDD - 34GB SCSI

-------------------------------------

Production DB size: 10.89 GB

Number of tables: 253

We are planning to get a new server/system and upgrade to 8.0 on it. What is the recommended system requirement for Postgres 8.0?

Please give me your inputs on this.

Thanks

Saranya
