Sub-Millisecond Read Latency for EFS:

https://aws.amazon.com/blogs/aws/amazon-elastic-file-system-update-sub-millisecond-read-latency/

Up until today, EFS latency for read operations (both data and metadata) was typically in the low single-digit milliseconds. Effective today, new and existing EFS file systems now provide average latency as low as 600 microseconds for the majority of read operations on data and metadata.
This performance boost applies to One Zone and Standard General Purpose EFS file systems. New or old, you will still get the same availability, durability, scalability, and strong read-after-write consistency that you have come to expect from EFS, at no additional cost and with no configuration changes.
