A new interpreter in Python 3.14 delivers a free speed boost
Briefly

Python 3.14 is set to launch later this year and will introduce a new interpreter that promises to increase performance by up to 30% with no required changes to existing code. It employs optimizations based on tail calls, not changing the language's definitions, but enhancing CPython's internal bytecode instruction dispatch mechanisms. These improvements don't necessitate recompilation of C extensions or alterations to APIs, ensuring that the transition remains seamless and low-maintenance, leveraging existing infrastructure without additional overhead.
Python 3.14 will feature a new interpreter that can enhance performance by up to 30% without requiring any modifications to existing code.
The interpreter's updates are primarily focused on optimizing bytecode instruction dispatching through a C compiler optimization technique.
