Python performance matters

Abstract

It's 2022. Moore's Law and Dennard scaling have run out of steam, making it harder than ever to achieve high performance - especially in Python. This talk first explains in detail the unique challenges that Python poses to programmers. It then presents Scalene, a novel high-performance CPU, GPU and memory profiler for Python that does many things that past Python profilers do not and cannot do. Scalene both runs orders of magnitude faster than other profilers while delivering more accurate and more actionable information that's especially valuable to Python programmers.
