While the common PyBench had regressed slightly from Python 3.12 to Python 3.13, for Python 3.14 its performance is looking quite good and ahead of those prior releases.

PyPerformance benchmark with settings of Benchmark: go. Python 3.14 was the fastest.

PyPerformance's go benchmark saw a very nice speed-up with Python 3.14.

PyPerformance benchmark with settings of Benchmark: chaos. Python 3.14 was the fastest.

Python3 continues seeing nice incremental gains almost with each new release.

PyPerformance benchmark with settings of Benchmark: float. Python 3.14 was the fastest.

The Python 3.13 to Python 3.14 performance gains were typically coming in as larger than going from Python 3.12 to Python 3.13.

PyPerformance benchmark with settings of Benchmark: nbody. Python 3.14 was the fastest.

Python 3.14 has been running solid in my benchmarks this week as well as from testing on Fedora 43 and other upcoming Linux distribution releases.
