Performance impact of using File Server Resource Manager on large volumes

A customer recently asked how performance is affected when you use File Server Resource Manager in R2 on large volumes. Based on our testing, here’s what to expect:

Quotas: Internal benchmarks have consistently shown I/O performance cost of less than 10% for tracking quotas on a volume. The cost remains fairly flat with volume size and number of quotas.

Screening: The I/O performance impact is negligible for this feature.

Reporting: Running reports can negatively impact server performance, though we do not have any hard benchmark data. It is recommended that storage reports be scheduled for off-peak hours.
