Traditional downloads are downloaded from the server, which is a one-to-one download method; while P2P downloads can use the resources downloaded by other people, and transfer the information needed by each other between the downloaders. Since all available ports can be used in this way, even up to 80 ports, for such type of downloads, especially Thunder download, it is recommended not to block traffic directly, but to control the maximum bandwidth at 20K to ensure that P2P downloads will not affect others.
