They do slow it down from the passenger perspective, but Ryanair optimise for the overall cost of turning planes around. Loading and unloading bags from the hold costs time and money. Transporting those bags from bag-drop to the plane means paying the airport for that privilege. Misplaced bags etc. adds a customer service overhead. Ryanair deliberately don't use jet bridges so they can load/unload from both ends using built-in stairs
