Cisco Transition from LISP to GRE (Or Other) Troubleshoot Tunnel Speed Issues

The tunnel and endpoints are up and running. Traffic flows in both directions and routes properly. I have a 400 mb/s pipe at the Cisco end and a much larger one at the cloud instance end. I was using LISP before in a similar situation and was getting 300+ mb/s. With the new setup I am down to 50 mb/s. I have checked CPU load on the router (<30%) and nload on the Linux Instance (Centos 7) shows the 50 mb/s with essentially zero CPU load.

I have calculated and deployed an MTU of 1476 for the Tunnel and 1436 as the MSS on both sides. (Client machines are still at 1500 default)

Essentially, I have a Instance announcing our /24 to the world via FRR/BGPd. That /24 is sent down the tunnel through a cable modem link to the Cisco and on via an unmanaged switch to the appropriate machines on the LAN. The return trip is the same.

Used to work fantastically using LISP on a slower 2851 Router, 350+ MB/s. Now using, an allegedly simpler, system on a faster 3945e router, it's very slow.

I need the link to function at least as good as before.
