Learn about the collaborative efforts between Microsoft and Meta-funded teams working simultaneously to enhance CPython performance through this 25-minute PyCon US conference talk. Discover how one team focuses on improving single-threaded performance through PEP 659 and PEP 744, while another tackles removing the global interpreter lock to enable better multi-core utilization via PEP 703. Explore the technical challenges of achieving both performance improvements simultaneously and understand the collaborative strategies employed, including maintaining open communication channels, sharing benchmarking code, allowing independent project development, and dedicating time to address the intersection of both initiatives. Gain insights into both high-level language runtime concepts and open source community management practices as Michael Droettboom and Dino Viehland demonstrate how coordinated teamwork can drive significant improvements to Python's performance across multiple dimensions.
