STINNER Victor <[EMAIL PROTECTED]> added the comment: Summary of unchanged Python (2.4 .. 2.7): * Mac: subprocess is 25 .. 50 times SLOWER than os.popen * Solaris : subprocess is 13 times SLOWER than os.popen * Windows XP : subprocess is 1.5 times FASTER than os.popen * Linux : (results are very close)
With a different buffer size: * Solaris : Popen(bufsize=-1) is FASTER than os.popen() * Mac : Popen(bufsize=1) and Popen(bufsize=8192) are a little bit slower than os.popen(), but much FASTER than Popen(bufsize=0) Notes: - PyFile_SetBufSize(bufsize) does nothing if bufsize < 0: keep system default (buffer of BUFSIZE bytes) - On Ubuntu Gutsy, system default (BUFSIZ) is 8192 bytes _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue4194> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
