jre7 can make it run a-little smoother, but it's not officially supported by the emu (and its still in development) but from my tests it mostly works (expect alot of gs corruption, and the viewport being really small (widescreen effect) when only ge is unchecked),
sometimes I swap the jre6 dir with the jre7 dir for quick testing., though unless you know what you're doing I wouldn't try this since you can break java and maybe even your system.
for jre6 you can try the launcher and checking UseConcMarkSweepGC and UseParNewGC might help reduce some pausing effects for a smoother feel, or for older cpu's try the parallel one
