My list of things to do included optimising GetRunningTransactionLocks(), run once per checkpoint.
I was thinking I needed to try harder to avoid acquiring LWlocks on all the lock partitions. ISTM that I don't need to do this - lwlocks on lock partitions are almost never contended now, so this should go much faster than before. Any thoughts? Do we think it would benefit from further tweaking? I'll assume not unless I hear from somebody with a different idea. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
