With this week’s release of Python 3.14 bringing performance improvements, debugging improvements, a new Zstd compression module, and other enhancements I have been eager to run some benchmarks seeing how Python 3.14 compares to prior Python releases.
For those curious about Python 3.14 performance benchmarks, I ran some fresh comparison benchmarks this week of the Python 3.12, Python 3.13, and Python 3.14 releases. All the Python releases were built from source in the same exact manner (optimized mode) on the same system and then tested with the same Python benchmarks in seeing how the performance of Python has changed over the past three releases/years.
All of these Python 3.14 performance comparison benchmarks were done on an AMD Ryzen 9 9950X3D desktop running Ubuntu 25.10 with the Linux 6.17 kernel.
Let’s continue for this brief look at the Python 3.14 performance.
