I agree there is a problem with BufFreelistLock (so please share your results with Heikki, who seems not to). As a result, I've published patches which reduce contention on that lock in various ways, all of which seem valid to me. There are lots of things we could have done for 9.2 but didn't, yet we have some things that did get done on the table right now so it would be useful to push those through immediately or at least defer discussion on other things until we get back around to this. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
