The msec/call number is awfully small to start with - and it doesn't change. How are you timing each function call? To what precision? You may be running fast enough on the new server that your measurement isn't precise enough and your code keeps adding zero time for each execution.

I don't think it's the SMP that's causing the problem, at least not directly.
