RT中的本地代码编译。
Also they often are implemented in native code and cannot be transformed in the "JRuby" way.
此外它们通常会以本地的代码来实现，因此不能以“JRuby”的方式做转换。
They aim to improve execution speed so that it is comparable to that of native code.
他们的目标是将脚本的执行速度提高到和本地代码(native code)一样快的水平。
The degree to which native code compilation affects application performance varies with the application, of course.
当然，本机代码编译对各个应用程序的性能的影响程度不尽相同。

But, clearly, some native code is still required.
但是，显然一些本机代码还是必需的。
In a future article, we will address the need for stateful invocations of native code and deal with issues around lifecycle management of the native code.
在后续的文章中，我们将解决本机代码的有状态调用需求，并且处理与本机代码的生命周期管理有关的问题。
However, communication between JVM and native code is generally slow, thus too many JNI calls can degrade performance.
不过，JVM与本机代码之间的通信通常很慢，因此，太多的JNI调用可能会降低性能。
