krause Still your score 163 well behind Nicolas' score of 97. Both are on same hardware, Pi 4 Model B, right? I don't think the amount of RAM would make a difference, still do you both have 4 GB?
Comparing the results I see that processor speed as measured, item 2, makes the difference. You got 0.961 whereas Nicolas needed 0.387 only. In fact yours is over the critical limit of 0.8. How could that be explained? The MoodleBox version, 3.0.0 vs. 3.1.0?
