Mirror download

what is mirror download mean and for? my brother downloaded mirror in 4min and i downloaded normal in an hour. What is the difference?

It’s I guess the same thing but for people who are having trouble downloading the normal one. It’s in the description.

ohh so is the download normally supposed to take an hour to do?

That’s for computers that can handle it. I’m not sure what the difference is. All it says is to download the mirror version if your computer isn’t downloading the first one properly.

It took about 20 minutes for me.
