I have sent a patch to patches list enabling concurrent vacuums to actually reclaim space while another long vacuum is running, i.e. vacuums won't no longer block each other from removing deleted tuples. see: http://archives.postgresql.org/pgsql-patches/2005-08/msg00304.php Could you perhaps test this patch as well, while you already have a setup for testing parallel vacuums under big loads ? Or perhaps you can share the setup/scripts/data so that I could run your test myself as well ? -- Hannu Krosing <[EMAIL PROTECTED]> ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
