I would like to understand how private free lists are "so much" faster. In fact, I don't recall if someone *measured* the performance speedup of these free lists :-) By the way, the Linux kernel uses a "SLAB" allocator for the most common object types like inode. I'm curious to know if CPython would benefit of a similar allocator for our most common object types? For example types which already use a free list. https://en.wikipedia.org/wiki/Slab_allocation Victor _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
