Dave Malcolm <dmalc...@redhat.com> added the comment: One possible use for this: mark the "str" buffers of PyUnicodeObject instances when demarshalling docstrings from disk; in theory these ought not to change, and can be quite large: the bulk of the memory overhead is stored in a separate allocation from the object, and thus isn't subjected to the ob_refcnt twiddling.
No idea if it's worth it though; the syscall overhead might slow down module import; also, KSM works at the level of 4K pages, and it's not clear that the allocations would line up nicely with pages. FWIW, various related ideas here: http://dmalcolm.livejournal.com/4183.html Again, no idea if these are worthwhile, this was a brainstorm on my blog, and some of the ideas would involve major surgery to CPython to implement. ---------- nosy: +dmalcolm _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9942> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
