有没有办法保存JAVA JIT信息以供下次运行，这样我就不必每天热身代码？
我有一个每天运行的 JAVA 进程，大约需要 1,000 或 2,000 次点击才能被 JIT 完全优化。我想做的是保存 JIT 信息，以便第二天它可以以优化状态启动。看起来这应该是可能的，但我还没有找到任何方法来做到这一点。
I have a JAVA process that runs every day and takes about 1,000 or 2,000 hits before it is fully optimized by the JIT. What I'd like to do is save the JIT info so that the next day it can start in an optimized state. It seems like this should be possible, but I have not been able to find any method for doing so.

您可以使用 JET 或 GCJ 等提前编译器，但我不认为有任何标准方法可以保存 JIT 形式。请记住，这将您的程序与您正在运行的架构联系起来，但听起来您已经意识到并接受了这一点。
You could use an ahead-of-time compiler like JET or GCJ, but I don't believe there's any standard way to save the JIT form. Keep in mind that this ties your program into the architecture you're running on, but it sounds like you're aware and accepting of this.
一种选择是控制方法被视为符合 JIT 编译条件所需的调用次数。
-XX:CompileThreshold（默认 10000）。
您可以使用各种值来调整您的应用程序。
请注意，不建议将其设置为零。
One option is to control the number of invocations needed for a method to be considered eligible for JIT compile.
-XX:CompileThreshold (default 10000).
You could play around various values to tune up with your application.
Please note that setting this to ZERO is NOT recommended.
你能让你的应用程序保持运行吗？如果您只是让应用程序休眠到第二天而不是关闭，会发生什么？然后，您将节省启动 JVM 的时间，并可能跳过抖动阶段。
Can you just keep your app running? What happens if you just have your app sleep until the next day rather than shutting down? You will then save time starting up the JVM as well as potentially skipping the jitting phase.
