yeah, i suspected something like that - the PREEMPT_RT latency numbers were so out of whack with anything i've measured on similar boxes. The debugging features on PREEMPT_RT are powerful but have a high overhead.
could you send me your PREEMPT_RT .config? (whichever version you have handy) That's the easiest way i can tell you which options to watch out for.
