Actually, the random versus sequential time may also be different depending on how many processes are competing for disk access, as well. If the OS isn't maintaining readahead for whatever reason, sequential access could, in theory, degrade to being the same speed as random access. It might be interesting to test this, too. cjs -- Curt Sampson <[EMAIL PROTECTED]> +81 90 7737 2974 http://www.netbsd.org Don't you know, in this new Dark Age, we're all light. --XTC ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
