Andrew, Matthew, thanks to you both four your advice. I'm sorry I couldn't 
provide more details to the situation, I will post again as soon I get them. 

Time to share your insights with the colleagues :)

Best Regards,

Betreff: Re: [PERFORM] Postgresql Hardware - Recommendations

For a database, I would almost always prioritize:
- I/O

So, fast drives (SCSI 10000RPM or better in a RAID configuration,  
more spindles == more throughput), then memory (more memory == more  
of the database off disk in cache == faster response), then more CPU  
(more concurrent request handling).
