Load average (which is presumably the metric in question) includes both processes using the CPU and processes waiting for I/O. So it *would* be strange for load average to go up like that, if database configuration remains the same (ie: equal query plans) -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
