I've done a lot browsing through pg_stat_activity, looking for queries that either hang around for a while or show up very often, and using explain to find out if they can use some assistance. You may also find that a dump and restore with a reconfiguration to mirrored drives speeds you up a lot - just from the dump and restore. > With hardware tuning, I am sure we can do better than 35Mb per sec.

If your database activity involves a lot of random i/o, 35Mb per second wouldn't be too bad. While conventional wisdom is that pg_xlog on its own drives (I know you meant plural :) ) is a big boost, in my particular case I could never get a a measurable boost that way. Obviously, YMMV. ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
