You obviously have never driven a diesel. It is harder to push the piston on the compression stroke on a diesel because of the higher compression ratio, but remember that it is pushing against a spring that pushes back just as hard on the way back down, effectively cancelling itself out. No throttle plate means far less pumping loss to slow the engine down.
Try driving a 10 year old diesel pickup down a hill (before they had standard equipped exhaust and/or transmission brakes): painful. The gas equivalents have much stronger braking.
