Billy,
   Hey, thanks for the tip. IT would be great to see this run better.

   I'm looking around in the kernel and haven't foudn SCHED_ISO vs.
SCHED_NORM. For the preemption model I chose 'Low Latency Desktop'. In
the .config file I see these entries:

#
# IO Schedulers
#
CONFIG_IOSCHED_NOOP=y
CONFIG_IOSCHED_AS=y
CONFIG_IOSCHED_DEADLINE=y
CONFIG_IOSCHED_CFQ=y

Am I supposed to choose one at the command line when booting? Or can I
change schedulers once the kernel is running, through /proc or
something?

If I cannot google something then I'll sign up for the ck list.

Thanks again to all who have answered. The info is helpful.

Cheers,
Mark
