    Performance questions

    No. In my application, there is no dynamical classes loading and there should be no JIT. This is to say, all classes have been pre-compiled into a single exe before the running. So....?

    Performance questions

    Two interesting questions on performance: 1. First time running of executive is significant slower than following running of same executive. For instance, first time executive running is 1 minute 22 second. But 2nd, 3rd running and so on is between 20-22 seconds. 2.Given equvalent size of codes(files in jar), time-cost of compiling are much different. Why and what make the performance big difference in above two questions? Thanks, Song
