I have exactly 4847 items in my archive. Most of these are personal documents, with a few books, movies, and songs in there as well. It takes me less than a minute for all of it to refresh. Are you sure it's your Manage Your Kindle page that's the problem? Could it be your computer? I'm sorry to say I don't know what could be causing it, but I don't think that it's normal.
Edit: dreams posted right before I did. So based on the information they provided, it's probably not the connection then.
