When navigating sites and subnets, expanding any of the left pane causes a delay in the information being displayed by several minutes. It makes it difficult to work with the interface.
The customer has well over 90 encompassed subnets. What the profile trace shows is that the NS is getting scopemembership
(spGetTrusteeScopeCollectionMembersbyResourceTypeGuid for each encompassed subnet and runs this exact query once for each encompassed subnet and each query is taking 1-2.5 seconds to complete.
No errors or notifications are displayed in the logs.
The issue is that most pages that lists all the subnets is that it gets the list of subnets and then does a complete Item load for each subnet.
Additionally within the tree the security of all subnets is rechecked at each node of the subnet tree. Given the large number of subnets that would be
expected in enterprise environments, this simply does not scale. There really is no SQL that can be improved other than to fix the code to not repeat work
that has already been done.
