INADA Naoki added the comment: How about increasing default value to 32KiB or 64KiB too?
binutils's cp works well for most cases, while it doesn't have option to specify blocksize. I want Python's copy functions works nice enough for common cases too. binutils cp uses 128KiB block for normal file. see more information in https://github.com/coreutils/coreutils/blob/master/src/ioblksize.h But copyfileobj can be used other file-likes. On Linux, typical socket buffer size is 128KiB, and typical pipe buffer size is 64KiB. So block size larger than 64KiB may cause unneeded blocking. That's why I suggested 32KiB or 64KiB. ---------- nosy: +inada.naoki _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29659> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
