Hi Mathew ,
I will be good if you could share some output pointing towards high cpu.Is the high cpu due to process or interrupts.
Show process cpu will be helpful.

CPU utilization is less than 20%

Best tool to use to identify bandwidth utilization and hosts involved is NetFlow. You can gather some stats directly from the router but it is best to actually use a NetFlow collector of some type. See your IOS docs on configuring NetFlow.
