By forcing administrators into thinking about the implications of adjusting the parallelism settings, you'd find that a lot of sites would run more smoothly as performance tuning would then become something done by default, as part of client setup.

I think default parallelism setting of 4 is a good starting point. That places an awful large onus on the client to keep tape moving in the drive at maximum speed. /C Why do you propose decreasing default parallelism setting to 1?

(It's safe to say that 7.2 or lower would be a different kettle of fish, as the introduction of nsrjobd played a significant part of adjusting the way performance is handled in NetWorker.)
