Probably, but it's a controversial area, and if you want to speed up a busy system, it would be almost the last thing to look at. Changing read-ahead settings would be almost the first thing to look at, as ways of improving the performance of Postgres by tweaking the operating system go. Increasing this parameter from the default is often very effective at speeding up sequential scans. -- Peter Geoghegan http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training and Services -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
