Actually, this issue is created to look for a generic approach that can optimize the running time for most, or even all, python scripts. Different scripts may import different modules, but this doesn't mean there isn't a method that works for all of them. > And many ideas like yours are already discussed on ML, again and again. I browsed about 6-7 threads on python-dev. I think 2-3 of them provide great information. But I don't think any of them gives concrete solutions. So we are still facing this problem today. > I want to close this issue. Please give us more concrete idea or patch with > target sample application you want to optimize. As said I'm looking for a generic approach. So optimizing specific applications isn't really the goal of this issue (though work on specific modules still helps). I did implement a proof of concept (link: <https://github.com/cykerway/pyforkexec>) for the fork-exec startup approach. It's still very rough and elementary, but proves this approach has its value. As Nick said: > ...the CPython runtime is highly configurable, so it's far from clear what, > if anything, could be shared from run to run... What I hope is we can inspect these configurations and figure out the invariants. This would help us make a clean environment as the forking base. If this is impossible, I think we can still fork from a known interpreter state chosen by the user script author. You may close this issue if nobody has more to say, but I hope the fork-exec startup can be standardized one day as I believe, for quick scripts, however much you optimize the cold start it can't be faster than a fork. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34296> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
