This reflects the results I get with a battery backed caching RAID controller as well, both Areca and LSI. Noop seemed to scale a little bit better for me than deadline with larger loads, but they were pretty much within a few % of each other either way. CFQ was also much slower for us. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
