Gareth Rees added the comment: Note that some filesystems (e.g. HFS+) don't support sparse files, so creating a large Arena will still be slow on these filesystems even if the file is created using ftruncate().
(This could be fixed, for the "fork" start method only, by using anonymous maps in that case.) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30919> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
