Hi @hyy0322 , I think now what we have is the total rateLimit just like you said. All download requests from other peers will be handled by *uploadManager.getDownload() function in which they will go through the same rate limiter *uploadManager.Limiter regardless of their peerID, you can refer to code below: https://github.com/dragonflyoss/Dragonfly2/blob/fbb6f1d081b4860760640cf345d0286c8b9c51f9/client/daemon/upload/upload_manager.go#L220-L226
