Pardon me for asking a potentially insulting questions, but have you
profiled your application so that you *know* why it's slow and where? 
If you find yourself getting bogged down in a couple of minor spots
which can be optimized, it may be worth it to simply optimize those
parts rather than risk the dangers of rewriting a system.
