It looks like you're just tracking the autovacuum process and not the actual vacuum subprocesses which it spawns. 2) The response time graphs would be more informative if you excluded the ramp-up portion of the test. As it is there are big spikes at the low end but it's not clear whether they're really part of the curve or due to ramp-up. This is especially visible in the stock-level graph where it throws off the whole y scale. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's On-Demand Production Tuning -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
