It sounds like your roller is not tight enough if you are concerned about not accelerating quickly. I tighten mine at least 3 full turns after the roller first touches the tire. It helps if you put some grease on the threads attached to the roller. If you want an independent check of power, time yourself up a steep hill (preferably with a constant grade) and use one of the online power calculators to estimate you power.
