Last week, @ch-2023 joined us to work on problem solving a drop in performance after upgrading from SpiceDB 1.13 to 1.25. @EvanCorkrean helped narrow down some potential causes, though we decided it would be easier to diagnose once they had more Otel traces available. Then, @rierevin had some questions about lookup_resources having some performance issues when a user had access to all resources. @EvanCorkrean took a look at the particular permission in their schema and suggested removing an intersection because that operator is heavy on lookup_resources.
