I'm not sure what causes this issue either, although I suspect it's the inter-CPU / CPU to memory communication speeds that make the difference. It seems that as the number of CPUs increase, the opteron lead increases over the xeon. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
