AWS VE edition throughput limit

Hi,

From this page: https://clouddocs.f5.com/cloud/public/v1/matrix.html it says that the max throughput for running BigIP VE in AWS is 20Gbps using the c5n.4xlarge instance type. Is that because the instance only does 25Gbps total? If it is run on a c5n.18xlarge which has a theoretical 100Gbps limit, is that achievable on the BigIP VE edition? Or is there a software limit preventing it from going beyond 20Gbps? We are only looking at running LTM on it.

Thanks!
