Also depends on the design of the roundabout. Those which are designed to make traffic flow efficiently do just that, and do it quite well (at least in my personal experience). Unfortunately, some highway departments are staffed by d**kheads who design them to be "traffic calming" devices - with too small a radius, reverse banking, etc - to impede traffic flow.
