As the comment in this method suggests, accumulating the value by repeated string concatenation is slow. Appending to a list speeds this up dramatically. To quantify this, downloading a 110Mb file from Apache take: ~3s using Internet Explorer 2.2s using wget 30mins using the script in http://mail.python.org/pipermail/python- dev/2009-September/091581.html With the attached patch applied, this time drops to 2.3s.
