有哪些优势和放大器;在.NET pre-Jitting组件缺点是什么？我听说，pre-jitting将提高性能。谁能解释时，pre-JIT和何时不pre-日新？

What are the advantages & disadvantages of Pre-Jitting assemblies in .NET? I heard that pre-jitting will improve performance. Can anyone explain when to Pre-Jit and when not to Pre-Jit?

推荐答案

pre-jitting或pre-编译会提高性能，在启动，因为你会可以跳过这一步。之所以说.NET JIT们每次一个应用程序及其库负荷，以便它可以在许多平台上，并提供最佳的优化架构上运行，而不需要管理你的构​​建。

"Pre-jitting" or pre-compiling will improve performance, at start up, because you would be skipping that step. The reason that .NET JITs every time an app and its libraries load is so that it can run on many platforms and architectures with the best possible optimizations without the need for managing your builds.

所以，你必须权衡是否值得管理员头疼为了节省几秒钟的应用程序启动和库加载。我认为最普通的用例这样做是为服务器安装在那里你会管理几台机器和环境非常稳定。例如。你不会pre-编译客户端应用程序，因为目标环境是不太predictable。

So you have to weigh whether it's worth the admin headaches to save a few seconds on app start up and library loads. I think the most common use case for doing this is for server installs where you tend to manage few machines and the environment is very stable. E.g. you would not pre-compile for client apps because the target environments are much less predictable.
