It would seem odd that any user you select showing available would then have a queue (with the exception of a small bug where it occasionally shows with slots but has a queue, but that is normally japanese users and normally they have a queue several thousand long)
however from where you went in to the room earlier, I have to agree with sam that your poor download performance could well be due to just sharing thousands of images, especially if you are trying to download films/music/etc, as many people will either check and see the images and block the upload, or will have programs set to automatically block you based on all of your upload slots being free (or a combination of both)
i think unsharing the images and sharing other files would certainly help
