Eko and all,
The MyIsam storage engine is a non transactional engine and InnoDb is
a transactional engine. That is the main difference. So I think the
MyIsam engine should be faster.
However, some file systems that have journals are faster than non
journalling file system. It's not always

Note that mysql does not support bind variables. If you think
you'reusing them, whatever API you are using is filling them in

Don't know if that's what you are trying to do. But I can't think of any
