El Capitan 10.11.6. With -s 20 (300MB) and 1GB of shared_buffers so as everything is on memory. Actually re-running the tests now with no VMs around and no apps, I am getting close to 9650~9700TPS with patch, and 9300~9400TPS on HEAD, so that's unlikely only noise. -- Michael -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
