Here's fresh results on more stressed hardware (on ext3) with 2.6.11-rc1-mm2 (which by the way has SCHED_ISO v2 included). The load hovering at 50% spikes at times close to 70 which tests the behaviour under iso throttling.
What version of JACK are you running (`jackd --version')?
You're still getting zero Delay Max. That is an important measure.
Ok updated jackd
Here's an updated set of runs. Not very impressive even with SCHED_FIFO, but the same from both policies.

I've updated the pretty graphs and removed the dud runs from here: http://ck.kolivas.org/patches/SCHED_ISO/iso2-benchmarks/
