App Engine uses a “precompilation” process with the Java bytecode of an app to enhance the performance of the app in the Java runtime environment. Precompiled code functions identically to the original bytecode.

有什么详细信息吗？

最佳答案

我在googlegroups message中发现了这个：

Yes,pre-compilation reduces the time to load an application. This will
benefit you on your first request after a deploy,after you’ve been cycled
out or if more application instances are created to scale up with your load.
You will see up to 30% improved loading time on your first request.
Pre-compilation works by doing a bit of class loading work ahead of time in
the App Engine environment before the request comes in.

因此,预编译似乎是关于优化加载时间,而不是运行时性能.
