Understanding the performance metrics of Amazon EFS on CloudWatch

Throughput is measured in MB/s, meaning the number of megabytes written or read per second. This metric is generally used to measure the speed of a read/write operation. Amazon EFS is a storage system, hence, this metric also counts within it. EFS is also unique, as mentioned previously, in that it is a network attached storage service. This means that information sent to write to EFS is via a network. So, any network latencies or deficiencies will have a grave effect on the throughput of an EFS instance.

Being that EFS is a network thing, this means that the number of clients connecting to the EFS storage service matters a lot. EFS has a way of monitoring the number of connections performing any type of I/O operations on it. Remember that EFS can be mounted on multiple EC2 instances, as well as on on-premise virtual machines. So, knowing the number of client connections is another important metric that is captured...
