The material and machine will determine what speeds and feeds are appropriate, simulation time should be pretty accurate, though if the cam program doesn't account for axis acceleration, it would be off some amount.
Imachining is for milling only (I think), it spirals down to the full cutter depth, and uses a constant stepover pattern, so that tool load is fairly constant while cutting.
This decreases machine time, and is easier on cutters.
