Hi, > Can you run bonnie++ version 1.03a on the machine and report the results > here?
Do you know if the figures from bonnie++ are able to measure the performance related to the overhead of the 'fsync' option? I had very strange performance differences between two Dell 1850 machines months ago, and raw performance (hdparm, not bonnie++) was similar, the only figure I could find with a significant difference able to explain the issue was the "await" compound reported by "iostat" - but I was still very much in the dark :/ http://archives.postgresql.org/pgsql-performance/2006-03/msg00407.php -- Guillaume Cottenceau Create your personal SMS or WAP Service - visit http://mobilefriends.ch/ ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
