Very different and hard-to-compare scenarios arise from these two different approaches: static vs. dynamic compilations and recompilations, the availability of precise information about the runtime environment and others. Java is often compiled just-in-time at runtime by the Java virtual machine, but may also be compiled ahead-of-time, as is
Consequently, you can install a 32-bit or 64-bit JVM on a 64-bit operating system. The primary advantage of running Java in a 64-bit environment is the larger address space. This allows for a much larger Java heap size and an increased maximum number of Java Threads, which is needed for certain kinds of large applications; however there is a ...

A graphical demo running as a benchmark of the OGRE engine. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
The JDK also comes with a complete Java Runtime Environment (JRE), usually called a private runtime, due to the fact that it is separated from the "regular" JRE and has extra contents. It consists of a Java virtual machine and all of the class libraries present in the production environment, as well as additional libraries only useful to ...

In a Java program, the memory footprint is predominantly made up of the runtime environment in the form of Java virtual machine (JVM) itself that is loaded indirectly when a Java application launches. In addition, on most operating systems, disk files opened by an application too are read into the application's address space, thereby ...
