As the old saying goes "first make it run, then make it right, then make it fast".

So code away, and if it becomes too slow for your application, you start to profile, and identify your bottlenecks.

In many cases the choice of good algorithms and data structures buys you more than any micro optimizations.

If you're still interested in micro optimizations, you'll find plenty of them discussed here at the monastery (for example with this search).
