The only other environmental thing I can think of might be a virus detection issue. Is there a way to perhaps mark MAME to not be checked by your program? You may to try to start in a -window and see if that improves things. At the same time, watch your Task Manager to see what else might be running and possibly stealing MAME's thunder.
