We've always had an ahead-of-time compiler, to produce pre-compiled Ruby code in.class files. But there were a few things missing.
我们一直都有提前编译器，用于以。class文件的形式来生成预编译的Ruby代码。
The compiler doesn't blindly compile everything though I think it can be deployed as an ahead-of-time (AOT) compiler. It kicks in whenever method execution counters trip over some threshold.
虽然我认为可以将编译器部署为AOT（ahead-of-time）编译器，但它其实并不会盲目地编译所有东西，只有当方法执行计数器超过某个阈值时它才会生效。
How you provide this information depends upon whether you compile with the JIT (Just-in-Time) compiler or the AOT (Ahead-of-Time) compiler.
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。
The Ahead-of-Time (AOT) compiler can catch template errors early and improve performance by compiling at build time as you'll learn in this chapter.
而预编译(AOT)会在构建时编译，这样可以在早期截获模板错误，提高应用性能。
