Python urllib.urlretrieve vs. Perl getstore

[Adam S]

I have a Perl and a Python version of a program designed to fetch
large files (40MB) from a remote HTTP server.

Initial tests indicate that the Perl version, using getstore()
is 3-4 times faster than the Python version. Is there a reason
for this and is there another Python library HTTP file fetch
function I can use? I don't want to use FTP as there
is no anonymous logon for this server.

Best Regards,

Adam
