I don't really know. I know that swept wings don't like slow airspeeds and if you pull up at a slow airspeed you can increase your descent. Its probably just the difference in the way the planes are built and the different aerodynamic factors that come with bigger heavier planes.

Also could be the fact that airliners have different ref speeds for different conditions where a cessna you just go with the approach speed, maybe add a few knots for gust, and see what happens.
