I tend to agree. What kind of disk setup is under your data store? If it's RAID-5 or RAID-6 is it possibly degraded? I'd run iostat -xd 10 while the write load it high to see how your xlog partition %util compares to the main data store partition. Do you have your main data store partition under a battery backed caching RAID controller? Tell us what you can about your hardware setup. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
