Olivier Grisel <olivier.gri...@ensta.org> added the comment: Flushing the buffer at each frame commit will cause a medium-sized write every 64kB on average (instead of one big write at the end). So that might actually cause a performance regression for some users if the individual file-object writes induce significant overhead.
In practice though, latency inducing file objects like filesystem-backed ones are likely to derive from the [BufferedWriter](https://docs.python.org/3/library/io.html#io.BufferedWriter) base class and the only latency we should really care about it the one induced by the write call overhead itself in which case the 64kB frame / buffer size should be enough. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31993> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
