texte = Buy more RAM before you buy more CPU's. You need to get a very good feel for the size of the database(s) and the rate of growth. Until you have enough RAM that you are never swapping, you will never be able to maximize your usage of CPU's (I/O bound vs CPU bound). Also buy the fastest hard-drive subsystem you can (RAID 5, 10000RPM), for the same reasons. Sun should have specs on 2 vs 4 CPU's under load.I would recommend configuring a 2 CPU machine that you can later upgrade to 4, since the real world rarely is anything other than orthogonal to specs!John Peacock ____________________Reply Separator____________________ Subject: Multiple CPUs?

The question is: how many CPUs do we want? 2? 4? etc. Does it make any difference?
