Not true.  I would say being able to read, edit and reuse is most
important, then working correctly, then running fast enough.  Because
there are always going to be bugs that you don't find for a few months,
so even if you think it works correctly, you're probably wrong.  As for
working fast enough, being able to read the code makes it  much easier
to optimize it later IF you find out you have to.
