New submission from Germán Méndez Bravo <german...@gmail.com>: A call to `importlib.__import__()` normally locks the import for the module being worked on; this, however has a performance impact for modules that are already imported and fully initialized. An example of this are inline `__import__()` calls in a hot path that is called repeatedly during the life of the process.
Proposal: A two steps check in `importlib._bootstrap._find_and_load()` to avoid locking when the module has been already imported and it's ready. ---------- components: Library (Lib) messages: 388057 nosy: Kronuz priority: normal severity: normal status: open title: Optimize repeated calls to `__import__()` versions: Python 3.10, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43392> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
