autolab
Autolab running slower than before
Noticed by many TAs, an issue for both students and instructors. Viewing submissions takes much longer to load than it should. When grading assignments, TAs noticed that it takes a while for submission to load from view submissions page and when clicking from one submission to the next.
Do profiling of submissions view / actions to see which parts of the logic take up most time verify if code diff is making a meaningful difference in rendering
This is mostly due to the view taking a long time to load. We should minimise the number of times we iterate through instance variable arrays either through some sort of server-side pagination or caching.
