• Client-side load generated by Apache JMeter test plan
– Get user’s Moodle ID
– Get user’s list of courses
– Pause - 4 seconds
– View first course in the list
– Pause - 5 seconds
– View My Areas
– Pause - 10 seconds
– View the middle course from the My Areas list
• Server-side monitoring with NewRelic & Jet Profiler

7. F1-style performance runs
