Yes, although perhaps not as much as you'd get with a 64-bit build. You still get the ability to have more than 4GB worth of kernel-managed disk cache, and in many situations that's all the value of a 64-bit machine anyway. You can find lots and lots about that in the pgsql-performance archives. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
