Python 3.14 Lands A New Interpreter With 3~30% Faster Python Code

Merged last week for Python 3.14 is a new tail-call intepreter that aims to offer significantly better performance with around 10% faster performance in PyPerformance or around a 40% speed-up in Python-heavy benchmarks. This tail-call interpeter can even outperform the current Python JIT compiler but for maximum performance benefits Python should be built with Profile Guided Optimizations (PGO)...
