Not too shabby.
What this could REALLY benefit from is some optimization. It dropped down to only one or two frames a second on my machine, which isn't a very old machine. If you go into File > Compact and Save it will cut your file size down a bit and make it run faster on export. Also you can go through your flash and on each keyframe go to Modify > Shape > Optimize Shape to get rid of unnecessary corners and lines in your flash drawings. Both of these techniques will give you a smaller better running flash.
