"Up to 60 Gbps of total system bandwidth"
If I remember correctly, the ASR series have an internal data plane bandwidth limiter. So, you should be unable to obtain more than what I quoted, from Cisco, above. However, often the routers won't reach their full bandwidth capacity with some form of traffics. For example, if it's generating GRE, i.e. the tunnel is terminated on the router, and the router needs to fragment packets, this will often obtain less throughput. Or, if generating IPSec, again often the router won't obtain its full bandwidth rating (even if there's no fragmentation).
