{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Add additional GC related benchmark","articleBody":"Given this [performance regression in Python 3.14](https://github.com/python/cpython/issues/139951), it would be nice if we had a benchmark which would have more clearly shown it before final release.  I have a [new GC specific benchmark](https://github.com/python/pyperformance/pull/381) but it doesn't do things that would show this regression.\n\nWe should consider adding a new benchmark.  The key features would be:\n- creating a bunch of net new container objects, in order to trigger many, potentially young generation, collections\n- creating tuple objects that can be untracked by the GC, in order to avoid slowing down full collections\n\nIdeally we prefer to avoid a micro or synthetic benchmark and instead find some kind of real application that shows this regression.   E.g. near the 3.13 release, we found a GC regression shown by Sphinx building Python docs.  Something like that would be good.\n\n","author":{"url":"https://github.com/nascheme","@type":"Person","name":"nascheme"},"datePublished":"2025-10-28T18:20:04.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/437/pyperformance/issues/437"}
