I focus on making the code clear before anything else.  Then I make sure
it's correct -- this is much easier when it's already clear.  Then, if
it turns out to be necessary, I worry about making it fast -- again,
this is much easier if you have clear correct code to start from.

First rule of performance tuning: the problem is never where you thought
it was going to be.
