I can take a look when we run another test, but we pull roles from a custom table. So I don't think we really use the PAGS groups. We looked at metrics on the database during our tests and nothing like this really stood out. We did notice the aggregate data accounted for about 35% of all traffic to the database. My understanding of the code is the user attributes are cached for 1 minute which could probably be raised to a higher value.
