If I'm lucky, all the downloads will succeed. Most often at least one file will fail to download. This rate limiting may affect your mirror's visibility to the official mirror checker (causing your mirror to be marked as unreachable), and it may also cause problems for people who download updates from your mirror or do a netinstall with your mirror as the source. I would suggest increasing the maximum connection rates, if you want to keep rate limiting.
