Im using jigdo-lite to download a Debian DVD ISO. I already have the CD version of the image, so I added the CD files to the task. Now I need to download many files (not all) of the DVD ISO.

The default jigdo-lite uses wget to download files. It seems jigdo (wget) downloads only one file at a time with one connection. So I'm getting a low download speed.

How can I accelerate the download speed using jigdo?

Possible Solutions:

1. Using different download manager with jigdo. Is it possible? If yes, How?
2. Using jigdo (wget) to download multiple files at once. How?
3. Getting download links of remaining files to download so that they can be downloaded with a download manager and later added to jigdo iso. How?
