I wonder how much tuning like this , just changing thread priorities, which would effect the results of these tests. PREEMPT_RT is not pre-tuned for every situation , but the bests performance is achieved when the system is tuned. If any of these tests rely on a low priority thread, then we just raise the priority and you have better performance. These other systems like Vanilla 2.6.x , and I-pipe aren't massively tunable like PREEMPT_RT .
