I am still seeing the same performance as the OP when I use extractall() with a password protected ZIP of size 287 MB (containing one compressed movie file of size 297 MB). The total running time for extractall.py was real 35m24.448s user 34m52.423s sys 0m1.448s For a bash script using unzip -P the running time on the same file was real 0m19.026s user 0m8.359s sys 0m0.414s extractall.py loops over the contents of a directory using os.walk, identifies zip files by file extension and extracts a certain portion of the filename as password using a regex. If I leave the ZipFile.extractall part out of it and run it it takes 0.15 s. This is with Python 2.7.1 and Python 3.1.2 on Mac OS X 10.6.4 on an 8-core MacPro with 16 GB of RAM. The file is read from an attached USB drive. Maybe that makes a difference. I wish I could tell you more. This is just for the record. I don't expect this to be fixed. ---------- nosy: +andreb _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue3978> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
