If not, please let me know, and I can resubmit the proposal using the proper template.\n\n[prek](https://github.com/j178/prek) is a \"reimagined version of pre-commit, [...] designed to be a faster, dependency-free and drop-in alternative\".\nIt has already been adopted by major projects from Apache, FastAPI, and Django (see [prek/Who is using prek?](https://github.com/j178/prek#who-is-using-prek)).\n\nRunning prek against the entire CPython codebase yields a speedup of almost 2.5x without a cache and 1.25x with a warm cache.\n\n```shell\nhyperfine --warmup 2 --runs 5 \\\n  --prepare \"prek cache clean\" \"prek run --all-files\" \\\n  --prepare \"pre-commit clean\" \"pre-commit run --all-files\"\nBenchmark 1: prek run --all-files\n  Time (mean ± σ):     19.835 s ±  0.290 s    [User: 50.857 s, System: 6.248 s]\n  Range (min … max):   19.527 s … 20.201 s    5 runs\n\nBenchmark 2: pre-commit run --all-files\n  Time (mean ± σ):     48.944 s ±  0.448 s    [User: 76.063 s, System: 6.096 s]\n  Range (min … max):   48.522 s … 49.681 s    5 runs\n\nSummary\n  prek run --all-files ran\n    2.47 ± 0.04 times faster than pre-commit run --all-files\n```\n\n```shell\nhyperfine --warmup 2 --runs 5 \\\n  \"prek run --all-files\" \\\n  \"pre-commit run --all-files\"\nBenchmark 1: prek run --all-files\n  Time (mean ± σ):      6.763 s ±  0.124 s    [User: 35.990 s, System: 2.134 s]\n  Range (min … max):    6.589 s …  6.900 s    5 runs\n\nBenchmark 2: pre-commit run --all-files\n  Time (mean ± σ):      8.537 s ±  0.048 s    [User: 43.797 s, System: 1.903 s]\n  Range (min … max):    8.484 s …  8.608 s    5 runs\n\nSummary\n  prek run --all-files ran\n    1.26 ± 0.02 times faster than pre-commit run --all-files\n```\n\n\n### Has this already been discussed elsewhere?\n\nThis is a minor feature, which does not need previous discussion elsewhere\n\n### Links to previous discussion of this feature:\n\n_No response_\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-143149\n* gh-143359\n* gh-143360\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/juhannc","@type":"Person","name":"juhannc"},"datePublished":"2025-12-24T15:26:38.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":18},"url":"https://github.com/143148/cpython/issues/143148"}
