New submission from STINNER Victor <vstin...@python.org>:
Currently, the type lookup cache is shared by all interpreter which causes multiple issues: * The version tag is currently protected by the GIL, but it would require a new lock if the GIL is made per interpreter (bpo-40512) * Clearing the cache in an interpreter clears the cache in all interpreters * The cache has a fixed size of 4096 entries. The cache misses increase with the number of interpreters, since each interpreter has its own types. I propose to make the type lookup cache per interpreter. ---------- components: Interpreter Core, Subinterpreters messages: 383777 nosy: vstinner priority: normal severity: normal status: open title: [subinterpreters] Make the type lookup cache per-interpreter versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42745> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
