[$] Python performance myths and fairy tales

Antonio Cuni, who
is a longtime Python performance engineer and PyPy developer, gave a presentation at EuroPython
2025 about 'Myths and fairy tales around Python performance' on
the first day of the conference in Prague. As might be guessed from the
title, he thinks that much of the conventional wisdom about Python
performance is misleading at best. With lots of examples, he showed where
the real problems that he sees lie. He has come to the conclusion that memory
management will ultimately limit what can be done about Python performance,
but he has an
early-stage project called SPy that
might be a way toward a super-fast Python.
