## Python for Good >>> PyCon China 2022 大规模生产环境下的 Faster-CPython 主讲人：王文洋  HELLO WORLD  five. We aim to do this in four distinct stages, each stage increasing the speed of CPython by (approximately) (approximately) 50%. $$ 1.5**4\approx5 $$ Each stage will be targeted at a separate release of CPython. A faster schedule is possible, but we believe that predictable and reliable performance improvements

Falcon apps work with any WSGI server, and run like a champ under CPython 2.7/3.5+ and PyPy. ## How is Falcon different? We designed Falcon to support the demanding needs
