Hello, Wondering what's a good value for effective_io_concurrency when dealing with FusionIO drives...anyone have any experience with this? I know that SSDs vary from 10 channels to 30, and that 1 SSD about as fast as a 4-drive RAID, but I can't seem to settle on a good value to use for effective_io_concurrency. Has anyone done any performance testing/metrics with the value? Any recommendations or thoughts? --Richard -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
