How about if you do a whole slew of the UPDATEs and then stop those and run a bunch of SELECTs? (I don't think I've seen anything mentioned so far which rules out hint bit rewrites as an issue.) I see you have tweaked things to balance the writes -- you might want to try further adjustments to reduce backend writes and see what happens. -Kevin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
