Sorry, I was not realizing that is what I was doing. I read a post where 
someone suggested using a US-II based system if you want CPU hotswapping. I 
simply gave my arguments on why I thought it was a bad idea.

It is a valid benchmark though :-) compile speed is a actually a good measure 
for any integer app that is small enough to run in large cache... Image 
processing, oil companies for their simulations, cad... they all act very 
similar to compile benchmark - if a compile is twice as fast, a software 
image rendering is usually twice as fast too :-)

If you run databases or so, then yes, your comment is valid.

Fair enough :-)
