Both methods get_activity_link() and get_grade_analysis_url() now cache the results of the check whether the activity module provides grade.php or not. Previously, get_activity_link() called file_exists() in every call and get_grade_analysis_url() did not check the existence at all. Note that this solution is still sub-optimal as apparently both methods do very similar job. This should be refactored one day by a brave developer who works on gradebook. Meanwhile, even this suboptimal solution is more effective than the previous one for most courses.
