[issue11114] file.tell extremely slow

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

That's expected. seek() and tell() on text (unicode) files are slow by construction. You should open your file in binary mode instead, if you want to do any seeking.

Maybe I should add a note in http://docs.python.org/dev/library/io.html#performance
