Python 3.14 shows significant performance improvements over previous versions, running approximately 27% faster than 3.13 in recursive workloads. The free-threading interpreter delivers 2-3x speedups for CPU-intensive multi-threaded applications by removing the GIL, while the JIT compiler shows minimal gains in these tests. Python 3.11+ versions remain substantially faster than 3.10 and earlier. PyPy continues to outperform CPython by 5-18x depending on the workload, though still trails compiled languages like Rust.

Python 3.14 Is Here. How Fast Is It?

It's faster than 3.13 but still depressing.

Never understood the people still complaining about Python’s speed. Obviously, the usecases are where the language’s speed is not going to be the biggest bottleneck, but rather the network bottlenecks (e.g. querying a DB), or time lost on developing software.
I think the core team is doing an amazing job at improving the language and optimizing computations, without breaking existing solutions. Really, if you ever have doubts, open one of their changelogs and you will see how much effort and what improvements they offer each release. The popularity of Python, as far as I understand, came exactly with the strategic decisions to make it a language where it is easy to contribute to the community and do it so by following common practices (as came with PEP), and providing backwards-compatibility (except Python 2-&gt;3). I was a C/C++ developer before, we don’t have it so well, many often follow styleguides by corporations such as Google, certain versions can differ significantly and I personally never managed to develop a C “package” to share that would be used by others; unlike with Python. One can argue that many ideas weren’t original (e.g. came from JavaScript, or Java), but they improve the language always in accordance with what they believe is most well-received by the community.
Python 4 could come and many would still be complaining (<a href="https://builtin.com/software-engineering-perspectives/python-4" target="_blank" rel="noopener nofollow">which is not coming in the foreseeable future</a>).
