I need to compare performance between preempt_rt, Xenomai and RTAI patches. Each of them has their own tests, but they do not give similar results, and not all tests are available on all three platforms. What I'm looking for is a benchmark that will measure basic performance like interrupt latency, context switch time, etc., And it will work on all three platforms. I tried to execute the Thread-Metric metric , but for me it was too complicated. Does anyone know if such a criterion exists? Thanks in advance for any help.
