They can indeed. However, in this case the biggest factor is the none use of ithreads. In the tests we did here we did a like for like test, which showed a significant improvement when we simply recompiled without ithread support. If we were to add compiler flags I'm sure we could improve further, but as others have mentioned, adding further optimisations could have side effects.

    I would expect the real gain to come from getting rid of PERL_IMPLICIT_CONTEXT/MULTIPLICITY (in addition to ithreads). Can you show perl -V from your tests?
