Testing Instructions:
Hide

This will be tested by CI and the performance testing servers

For specific testing this requires reverting the commit and comparing the number of DB calls.
One easy place to do so is on the front page of any assignment.

View an assignment

Refresh the page a few times until the DB read count stabilises

Take note of the number of DB reads

Revert the patch

Refresh the page a few times until the DB read count stabilises

Confirm that the read count when the patch is present is lower than without it.

Description

Advanced grading uses get_context_info_array to get modname
This is stupidly expensive and we can easily cut out multiple queries by using get_fast_modinfo() as we almost always have this information cached.
