INADA Naoki <songofaca...@gmail.com> added the comment: Since normal dict preserves insertion order, OrderedDict usage will be decreased. So I don't think 2x memory consumption is big issue.
BTW, functools.lru_cache uses custom doubly-linked list which is much memory inefficient. Rewriting it to use OrderedDict will reduce memory usage significantly. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31265> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
