Impressive, but I don't think we every determined conclusively whether our EFS problems were caused by throughput or latency.
Also, throughput is going to be limited by your instance type, right? Though that might also be the case for EBS. I can't remember. Part of the problem is AWS performance is so confusing.
EBS connects to EC2 via a separate pipeline, different from the EC2 instance Networking bandwidth. This is true for all Nitro instances.
EFS / FSx connects to EC2 via Networking bandwidth. So you should refer to that if you are looking for the bandwidth information.
