So somewhere between 6 and 12 disks we go from significant IOWAIT to nearly none. Given that CPU bound workloads deteriorate more gracefully than IO Bound, I'm pretty happy having enough extra IO bandwidth on this machine. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
