Managing file system throughput - Amazon Elastic File System

Managing file system throughput

You can modify the file system throughput mode after you create it. There are two throughput modes to choose from for your file system, Bursting Throughput and Provisioned Throughput. With Bursting Throughput mode, throughput scales as the size of your file system in the standard storage class grows. For more information about EFS storage classes, see EFS storage classes. With Provisioned Throughput mode, you can instantly provision the throughput of your file system (in MiB/s) independent of the amount of data stored. For more information about Amazon EFS throughput modes, see Throughput modes.


You can decrease your file system throughput in Provisioned Throughput mode as long as it’s been more than 24 hours since the last decrease. Additionally, you can change between Provisioned Throughput mode and the default Bursting Throughput mode as long as it’s been more than 24 hours since the last throughput mode change.

You can manage the file system throughput mode using the Amazon EFS console, the CLI, and API.
