How to replicate: course with 10 students, 7 groups, 30 samigo assessments all sent to gradebook
Go to Gradebook as admin user... load will take close to 1 minute
Debugging reveals 49,000+ queries asking for AnswerFeedback info.......... IT seems clear that Hibernate eager loading is loading every single aspect when we are asking for simple info like isAssignmentDefined.
Here is a query I saw executed 49,568 times while loading the Gradebook only (not going into Samigo at all):
