Comment on YJIT: Building a New JIT Compiler for CRubyparent

Comments

Python does, via pypy [1], which has very impressive performance and Python3 support. However, there are some subtle drawbacks, e.g., building from source takes hours instead of seconds (like CPython), and C extensions are slower. Still, the performance of pypy on a wide range of pure Python microbenchmarks is extremely impressive, and comparable to V8 (I've been collecting such benchmarks at [2] lately).
