I'll add another 2 cents to yours.

Refactoring and increasing the OO of nearly anything will increase the 
time.  Method calls are expensive, and so is object creation; as long as 
this is true, OO with minimal redundant code will always be slower than, 
say, procedural programming.

That said, speed isn't OO's strength: maintainability and reuse are.  And 
if you've got good design and style, it can be easier to understand code 
you haven't seen before.
