The results on the website were updated on August 28 to fix this flaw and to incorporate some suggestions made on the pgsql-performance list (see http://www.potentialtech.com/wmoran/postgresql.php). I don't know why he didn't report back to the list. He expressed the desire that BSD benchmark faster than Linux, but the Linux numbers he reports are still about 8-10% better than the FreeBSD numbers. Both BSD and Linux are undergoing rapid development so this is pretty close to even. ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
