Resources and performance
Reading time: 1minThe resource consumption of WirisQuizzes for Moodle depends on Moodle’s own resource consumption, and it depends powerfully on how WirisQuizzes for Moodle is used.
For example, in a time-based exam, where all students start simultaneously, many initial connections are expected at the beginning. The connections will slow down after some minutes, and there will be a peak by the end of the examination. Despite the high dependence on the type of usage, the following rule holds
| 4 core + 3GB RAM | 360 questions/minute |
Note
Calculations are done with a questionnaire of 10 WirisQuizzes questions (5 random, 5 non-random). Maximum CPU load: 80%. Average CPU load: 50%. WirisQuizzes and MathType services from our wiris.net servers
Typical scenario
We assume each questionnaire contains 10 questions (5 non-random and 5 random), and the student needs an average of 30 minutes to solve each questionnaire. Students can start the questionnaire whenever they want. We don't expect a peak at any time. As a result,

To summarize, 4 cores with 3GB RAM can deliver 1080 questionnaires simultaneously, under the given conditions. Now, following the above rule, we can make other estimates:
| Concurrent Users | CPU cores | RAM (GB) |
|---|---|---|
| 540 | 2 | 2 |
| 1080 | 4 | 3 |
| 2160 | 8 | 6 |
