One of the most obvious symptoms is that `pathlib.PurePath` objects are slow to construct. We should be able to speed construction up without making other parts of pathlib slower.\r\n\r\nTwo possible approaches:\r\n\r\n1. Optimize the existing machinary of path construction: `__new__()`, `_from_parts()`, `_parse_parts()`, `_parse_args()`.\r\n2. Perform less work in the constructor: defer parsing, joining and normalization until needed.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-101560\n* gh-101664\n* gh-101665\n* gh-101667\n* gh-102476\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/barneygale","@type":"Person","name":"barneygale"},"datePublished":"2023-01-27T02:24:40.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/101362/cpython/issues/101362"}
