Actually it makes perfect sense. Running non-realtime JACK threads SCHED_FIFO will do the most harm. The others less. I predict that using normal jackd -R (without schedtool) will produce the same results running SCHED_FIFO and SCHED_ISO (within the normal variance). I think schedtool is too blunt and instrument for making these measurements. -- joq - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
