Suggested conclusion: accelerator priority is of little relevance, DWC improves block writes significantly,
but has little-to-no other effect.

On the P200, no apparent performance gain with DWC on. Accelerator ratio is fixed on this
controller. Stripe size may have an effect, will not be tested now...
