I'm slightly worried that the results for COPY aren't anywhere near as good as the SELECT and VACUUM results. It isn't clear from those numbers that the benefit really is significant. Are you thinking that having COPY avoid cache spoiling is a benefit just of itself? Or do you see a pattern of benefit from your other runs? (BTW what was wal_buffers set to? At least twice the ring buffer size, hopefully). -- Simon Riggs EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
