That will have a massive, massive effect on performance. Depending on your RAID subsystem, you can except RAID-0 to be between two and twenty times as fast for writes as RAID-5. If you compared one filesystem on RAID-5 and another on RAID-0, your results are likely not at all indicative of file system performance. Note that I've redirected followups to the pgsql-performance list. Avoiding cross-posting would be nice, since I am getting lots of duplicate messages these days. 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
