The two methods are not even remotely equivalent, the bandwidth you get over CIFS versus sending screen drawing info are radically different. There are some msdn articles and blog entries on the topic, see https://blogs.technet.microsoft.com/askperf/2009/04/17/terminal-services-and-graphically-intensive-applications/ for example.
