STINNER Victor <vstin...@python.org> added the comment:
It would be interested to see if using _PyBytesWriter in bz2, lzma, zlib and _io.FileIO.readall() would speed up the code. I would prefer to centralize the buffer allocation logic in _PyBytesWriter rather than having custom code in each file. _PyBytesWriter is designed to reduce the number of realloc() by using overallocation, it uses a different overallocation ratio on Windows, and it uses a small buffer allocated on the stack for strings up to 512 bytes. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41486> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
