Therefore, it's impossible to put `sys._stats_on`/`sys._stats_off` calls around tested code and get the results out.\r\n- Since stats collection is on by default, it is very fiddly to exclude code for stats, especially for things that fire off subprocesses, e.g. pyperformance.\r\n\r\n@markshannon's [suggestion](https://github.com/faster-cpython/ideas/issues/511) is to:\r\n\r\n- Having stats off by default\r\n- Add an `-Xstats` flag to turn it on at startup\r\n- Always dump out stats\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-100144\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/mdboom","@type":"Person","name":"mdboom"},"datePublished":"2022-12-09T18:44:00.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/100143/cpython/issues/100143"}
