Python, 但Restrain是不同的。 我把Restrain的特性称为 “CPython Compatible” Working With Existing And Prospective C-Extensions 兼容C extensions, 尽管不能优化, 但可以做到调用的开销尽可能接近CPython 版本 # Keeping The Same Semantics As The Original

## 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
