We have a CSR deployed in AWS and it is handling about 100-200 Mbps of traffic.
Looking at AWS CloudWatch Monitoring, the EC2 instance hosting the CSR is running at 15-20% (see attached). And looking at the CPU utilization from the CSR console, I see 0%.

Which one should I trust?
Thanks

Thanks for the feedback Alan.
Will open a case with Cisco to get an official answer from them. Will let you know if I get anything interesting.

What you are seeing from CSR is the CPU utilization of IOS. On the CSR, IOS is only the Control Plane. Most of the heavy lifting is done in the Data Plane. There is another command that can show data plane utilization: "show plat h q a datapath utilization".

The CPU utilization from Cloudwatch is about 20%. It is passing about 100 Mbps. The load from your command shows 2%.
