More importantly , if compilation runs in the middle of your test run , your test result will be the sum of some amount of interpreted execution , plus the jit compilation time , plus some amount of optimized execution , which doesn t give you much useful insight into the actual performance of your code 最重要的是,如果编译是在测试运行的过程当中进行的,那么测试结果就变成一定量的解释执行,加上jit编译时间,再加上一定量的优化执行的总时间和,这些并不能让您清楚代码的真正性能。
It would be highly valuable to investigate a sort of jit compilation technology that fits the embedded java virtual machine on mobile phones . this thesis analyzes the encountering problems from applying jit compilation to the embedded java virtual machine , designs and implements a jit optimizing solution for the mobile phones 因此,针对移动通信设备的特点,研究适合于嵌入式java虚拟机的即时编译优化技术,从而为各种j2me应用提供一个高性能的java运行平台,不仅具有重要的现实意义,而且有着良好的应用前景。
