While you are subscribed to Prime Plus at 30 Mbps down/ 2 MBps up, you can still see great affects in download speeds when capping that upload. This is the same regardless of subscribed tier, etc. Every download action will still require some small upload. Since this resource is eaten up in back ups, other actions are queued. When requesting information to be downloaded- anything from files, to streaming, to browsing, your also sending (uploading) small packets to confirm receipt of the data, request more data, etc. If all of your provisioned upstream bandwidth is tied up in backing up Google Drive, etc., then these necessary actions will take longer. In essence, it is not your downloading that is suffering but, rather, a great delay in the paired upload requests that are paired with such actions.
