• 解释器(Interpreter):当程序需要迅速启动时,使用解释器解释字节码,节省编译的时间,快速执行。 • JIT编译器(JIT Compiler):在程序启动后并且长时间提供服务时,JIT将越来越多的代码编译为本地机器码,获得更高的执行效率。 Java程序在JVM上执行的过程如下图所示: 编...

Tiered compilation, introduced in Java SE 7, brings client startup speeds to the server VM. Normally, a server VM uses the interpreter to collect profiling information about methods that is fed into the compiler. In the tiered scheme, in addition to the interpreter, the client compiler is use...
Compilation to native code is disabled, and all bytecode is executed by the interpreter. The performance benefits offered by the just in time (JIT) compiler are not present in this mode. -Xinternalversion Displays more detailed JVM version information than the -version option, and then exits....
