- Python 3.14 shows significant performance improvements over previous versions, with a 27% speed increase compared to Python 3.13.
- The free-threading interpreter in Python 3.14 demonstrates notable performance gains for CPU-heavy multi-threaded applications, running about 3.1x faster than the standard interpreter in Fibonacci tests.
- The JIT interpreter in Python 3.14 does not show significant performance improvements in the benchmark tests, suggesting it may need further development.
- Pypy continues to outperform CPython, being nearly 5x faster in Fibonacci tests and 18x faster in bubble sort tests compared to Python 3.14.
- Rust significantly outperforms all Python versions and Pypy, being up to 69.82x faster in Fibonacci tests and 36.15x faster in bubble sort tests.
- Python 3.11 marked a turning point in performance, moving Python from 'very slow' to 'not so slow'.
- The benchmark highlights the importance of considering specific use cases when evaluating interpreter performance, as results vary between single-threaded and multi-threaded applications.
