I have seen no difference in performance. Now, if you want large memory for a DB server, and you should, 64 is the way to go. I'm currently running CentOS 5 64-Bit vm's for the SaaS app I support. Works great on ESX 4U1. -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 512-248-2683 E-Mail: ler@xxxxxxxxxx US Mail: 430 Valona Loop, Round Rock, TX 78681-3893 -----Original Message----- From: pgsql-general-owner@xxxxxxxxxxxxxx [mailto:pgsql-general-owner@xxxxxxxxxxxxxx] On Behalf Of Bjørn T Johansen Sent: Thursday, January 21, 2010 1:07 AM To: pgsql-general@xxxxxxxxxxxxxx Subject: 64bits or 32 bits on ESX? We are going to be setting up a PostgreSQL server on a guest under VMWare ESX 4... Is there any performance improvement by choosing 64bits Linux over 32bits Linux as the guest OS or is it almost the same?
