Simulated Load
When running cyclictest, there needs to be enough load on the test system for the statistical delay to be meaningful. The load can be simulated using the Hackbench tool provided in the rt-tests source package, the official load simulation script, and the stress-ng tool.
Execute the following command for details:
Hackbench: run ./hackbench --help under the path rt-test/

Cyclictest mainly tests the real-time performance at the system level. For OpenPLC runtime, some more detailed testing methods are needed.
