The weekend package switch uses Python 3.14's new interpreter and, with compatible compilers such as GCC 16, can deliver roughly 5% to 15% faster performance.
CachyOS said users need only install the latest packages, with no further configuration changes required to benefit from the update.
The tail-call interpreter debuted as an option in Python 3.14, following a CPython pull request last year that outlined its design and significant performance gains across workloads.
What are the stability risks of using Python's newest features with the brand-new GCC 16 compiler?
As Rust rewrites offer 100x speedups, are small interpreter gains becoming irrelevant for Python's performance future?
With Python's JIT compiler already outpacing it, is this new tail-call optimization just a temporary performance fix?
