The measurements made are all in low numbers of MB and the results show that Clock is roughly same or better for large caches, but one might read them multiple ways. The zone of interest for us is above 1GB and the issues we care about are contention, so even if we think ClockPro has a chance of improving things we really don't have any measurements that support the cases we care about. -- 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
