High Performance solutions are needed to do things like urlretrieve

[David]

urlretrieve works fine.  However, when file size get very large.  It
goes on forever, and even fails.

For instance, one of download .zip file is of 363,096KB.

Particularly, when trying to get, with urlretrieve, a zipped folder of
a very large size, it could take up to 20 to 30 minutes.  Often it
fails, never any problem with smaller folders.  Any solution for this?

Regards.
