Performance and speed

Hi
First off I'd like to say that I think it is fantastic that you developers use your spare time to create such great free magic software for us addicts. I like the look of the program and think it has great potential. Actually like the interface better than the new MTGO beta wide.
However I am having some problems with the speed performance of the application. I consider myself a fairly patient man, but each time I hit space it takes 2-6 seconds for the app to go from one phase to another. Driving me nuts
Is this a known issue or is it something at my end? Is there something I can do to make it run faster/smoother.
My computer is not state of the art but not too shabby:
Intel i7 q740 or qm740 maybe, 1,73 ghz
16gb ram
Windows 8, Java JRE7
ATI mobility Radeon HD 5800 Series
