CONTAP-199704: Slow qtree statistics queries with very high qtree counts
Issue
When a system has a very high number of qtrees, querying qtree statistics through the REST API can take a long time. This can affect tools that collect qtree statistics, such as Harvest. The issue affects ONTAP 9.12.0 and later; the release assessment notes that the performance behavior is relevant from ONTAP 9.16, when the manual tables were introduced. The precise affected-version scope is unclear from the available defect information.
