Well, in the past I had quite the opposite experiences. Jigdo downloads
a lot of small files, and one extra HTTP query per file presents a
_huge_ overhead. Downloading an image with jigdo is at least 2-4 times
slower than downloading the single ISO image from the very same mirror.
The interesting effect is that the faster your network connection the
bigger the difference in speed will be.

You can help somewhat if you increase the number of files to process in
a batch (back when I played with it I had to edit the jigdo script for
this; I don´t remember the numbers but about a 10 times increase
noticably reduced the download time).

Jigdo helps only if you already have an older version of the image and
there are not much updates.
