Python 3.13 might introduce a Just-in-Time (JIT) compiler to enhance code performance.
The JIT compiler compiles code into machine code on demand, removing the need for a bytecode interpreter loop.
The new JIT compiler, a copy-and-patch JIT approach, converts high-level bytecodes into lower-level instructions in an Intermediate Language (IL) to optimize code execution.
Initial benchmarks indicate a 2-9% performance improvement, although the impact on benchmarks may not be substantial.
This JIT compiler lays the foundation for future significant optimizations in Python.
The Python community is actively discussing and exploring topics related to performance optimization and the use of JIT compilers.
Python 3.13 introduces a new JIT compiler called "copy-and-patch JIT," which is generating excitement and interest.
The discussions cover a wide range of topics including Python development under Microsoft, the impact of long-running processes, JIT compilation benefits and challenges, confusion between JIT and AOT compilation, type declarations, performance comparisons, package management challenges, and the trade-offs between C and Python for performance-critical code.
United Airlines has discovered loose bolts and other parts on the plug doors of its Boeing 737 Max 9 jets during inspections following a rapid depressurization incident on an Alaska Airlines plane of the same model.
