What are the steps to reproduce your problem?
1. Create a dashboard and save it
2. Open the dashboard and record the response time for the {{/api/share/dashboard/<id>/isAuthorizedToShare}] call
3. Create a significant amount of reports (>1k) not even related to the dashboard
What is the problem?
4. Reload the dashboard => response time increased signficantly
What would be the expected behavior:
The dashboard share authorization check should not be related to the global report count but at most to the report count within the dashboard the check is performed for.
