现在JRuby中有2048个方法采用即时编译，而提前编译能减轻这一限制。

Currently, just in time compilation in JRuby is restricted to 2048 methods, ahead of time compiling can help to mitigate that restriction.

本机代码在应用程序运行时由即时(JIT)编译器编译(而且可以重新编译)，基于经常调用的类和方法。

Native code is compiled (and can be recompiled) by a Just-in-time (JIT) compiler while the application runs, based on which classes and methods are invoked frequently.

你如何提供这些信息取决于你使用的是JiT(即时)编译器还是AoT(预先)编译器。

How you provide this information depends upon whether you compile with the JIT (Just-in-Time) compiler or the AOT (Ahead-of-Time) compiler.
