How does RMS usage of the global catalog for group expansion affect global catalog server performance?
The RMS server will cache any group expansion lists so this should not place a large load on the global catalog server. Frequent updates to group membership increases reliance on the global catalog server, although the time-out to acquire new group listings is configurable through the registry. Frequent expansion of large groups will degrade performance. For more information, see “Changing Active Directory Cache Settings “in “RMS: Operations” in this documentation collection.
