The current test plan is too restrictive and requires users to edit the .jmx to change (for example the rampup period) if they modify the values the runs can not be compared anymore with the standard XS, S, M, L, XL, XXL but users may be interested in change them for their own purposes. We can add more options to the test runner so users can easily change them.

Created https://github.com/moodlehq/moodle-performance-comparison/issues/1 to notice when values that can affect what users are interested in comparing have changed (also use group and description options would be good, but at least we can automate this part)

This modification will also require a modification in https://github.com/moodlehq/moodle-performance-comparison side to add extra arguments to test_runner.sh command.
