If yes, why are they all RT - they can have no expectation of >good latencies with a possible load factor of 140! In practice, didn't we want most tasks to behave like RT? (for interactivity purposes) -- I recall hearing that's basically what good interactivity meant; short reponse times to events. So then, taking await batch/bacground data-munching jobs, we fold back to needing a good RT-like behaviour. And then we can reach > 140. -- Inaky
