Throughput on Amazon EFS scales as a file system grows. A file system can drive throughput continuously at its baseline rate. Additionally, Amazon EFS is designed to burst to high throughput levels for periods of time.
For full documentation on EFS performance, see Throughput Scaling in Amazon EFS.
Amazon EFS uses a credit system to determine when file systems can burst. Each file system earns credits over time at a baseline rate that is determined by the size of the file system, and uses credits whenever it reads or writes data. Whenever a file system is inactive or driving throughput below its baseline rate, the file system accumulates burst credits.
If your file system has no burst credits available, the I/O throughput is the baseline rate, until burst credits replenish. The baseline rate may severely impact Artifactory performance. Therefore, it is best practice to avoid needing burst credits at all, or very rarely, and instead be able to provide the entire needed throughput with the baseline throughput allocation. You can monitor the balance by using Amazon CloudWatch metric for Amazon EFS.
