Some time ago i made some strange (well at least unexpected) discoveries.
When i was working with the code generator for the C-compiler i just tried to
remove the "align" instruction before every procedure start. Just to see how
much improvement the align did. BUT !!!! Imagine my suprise when i found out
that a "typical" program gained 1-3% in speed when the "align" instructions
was removed. Can anyone give some anwers on that ??
