"Suppose you had an automatic tool that optimizes Java code for your target platform before execution. Free of resource constraints inherent to run time optimizers, it processes all the code and optimizes it well.
You feed the application's classes to the tool, which optimizes them for performance and saves the results to disk. Now, you can deploy your Java application in optimized form so that it runs fast from the start on target systems.
...
Using the Excelsior JET Optimizer, you convert the classes into highly optimized x86 code and create a native executable for Windows or Linux. This technique is called Ahead-Of-Time (AOT) compilation. "
