Well, I was specifically interested in testing if half of raw sync time was a widely useful setting, across a variety of different, though representative I/O subsystems. Unfortunately, without some context about raw sync speed to go along with your numbers, I cannot advance or disprove that idea. It would also have been nice to see a baseline number of 0 too, to get an idea of how effective commit_delay may now be. However, that's secondary. -- Peter Geoghegan http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training and Services -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
