It would be beneficial to defer the string formatting operation and avoid incurring that overhead during task creation.\r\n\r\nThis can be done by storing the counter in the task struct, and using it to lazily populate the name in the `get_name` method.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-103767\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/itamaro","@type":"Person","name":"itamaro"},"datePublished":"2023-04-24T20:30:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/103793/cpython/issues/103793"}
