@dwpk20 It would appear so. Do you use a VPN by any chance? If so, local port forwarding will do nothing, as everything passes through the VPN, so the VPN itself would need to support port forwarding.
If not, then everything should be in place as long as your computer's IP address on your local network does not change. Looking at your profile though, it would seem it may have to do with how many other torrents you are seeding and the way your torrent client and the system will prioritize traffic. If other torrents are getting a higher priority, your speed on the uploaded torrent may fall once it gets there, in part due to the speeds of the other peers in the pool. This is not unusual.
