You might end up having to sum the traffic statistics for all of the logical interfaces (mt, pd, pe, ls, lt, gr, etc.) that are provided by the specific Tunnel or Services PIC.

The throughput capabilities will depend on the type and model of Tunnel or Services PIC that is providing the mt interface. I'm not sure the 800 Mbps output you see in 'show interface'  is an accurate reflection of the performance capability of the Tunnel or Services PIC. Tunnel PICs are generally limited by the aggregate FPC throughput of the FPC in which they are installed rather than having a PIC-specific throughput limitation.
