With the hardware and load you describe, I would guess you would limit context switching and see best performance with a connection pool that queues requests, keeping the actual connections to the database around 30. You only have so many resources available; having a large number of queries all contending for them is less efficient than having just enough queries active to keep them all busy. I have typically seen the plateau fall off to degradation at or before (CPU count * 2) + (spindle count). -Kevin
