STINNER Victor <vstin...@python.org> added the comment:
I expect that for objects which are not commonly modified by two interpreters "at the same time", it should be fine. But None, True, small integer singletons, latin-1 str single character singletons, etc. objects are likely to be frequently accessed and so can become a bottleneck. Moreover, Python has an infamous feature: write (modify ob_refcnt) on "read-only" access :-D See "Copy-on-Read" feature popularized by Instagram ;-) https://instagram-engineering.com/copy-on-write-friendly-python-garbage-collection-ad6ed5233ddf ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39511> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
