Can u add free download speed regulator. If enabled speed is 80-100 if disabled users have full speed which u usually provide. That function can be removed from u if 2-3 week test is crash. And all people can independently to choose what speed for the users to expose. I think it is not hard to realize in the shortest timeframes. or u can fix that without any add for 2-3 weeks and if result will be awful retutn the speed back.
