I think this is strongly related to core count. The spinlock contention problems don't become really bad until you get up above 32 CPUs... at least from what I can tell so far. So I'm not surprised it was just a straight win on your machine... but thanks for verifying. It's helpful to have more data points. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
