I've found that on servers with multiple drives and the page file spread across them linux does pretty well when swapping out. Even going pretty far back, when I had 6 9G SCSI drives on an old Sparc 20 running RHEL with 256M ram the swapping was quite speedy with a 100M or so on each drive. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
