Correct when your issue is low-bandwidth or bandwidth cap. Jigdo cannot help, there... but a direct image download wouldn't, either: buying a DVD/BD set makes more sense. Jigdo is indeed a direct advantage for the Debian mirror network, and an indirect advantage to users that would download the image sets from the mirrors: we would [likely] not be able to provide the larger images *at all* nowadays on most mirrors. Jigdo solves that *important* issue. Jigdo can also be a direct advantage (as in: it will be much faster) for an user that has a close (or even local) mirror that does not carry the full DVD/BD images, though: it will download >95% of the data from the close mirror, and rsync whatever is missing from the (relatively few) mirrors that have the full images. Evidently, when the mirror closer to you also happens to mirror the full DVD/BD images, downloading those directly makes sense. -- Henrique Holschuh
