(Even with lots of system RAM, you *still* have to write the data back to the disk, and that takes time.) But that's only if you've got a small db that needs *really* high tps rates. I'd rather spend my money on enough system RAM to keep the active portion of my DB in the OS cache. - -- Ron Johnson, Jr. Jefferson LA USA Is "common sense" really valid?
