-server选项对HotSpot JVM有什么影响? [英] What's the effect of -server option for the HotSpot JVM?

问题描述

我找不到任何清晰的文档来说明在启动Sun HotSpot JVM时通过-server选项的确切效果.

I cannot find any clear documentation about the exact effect of passing the -server option when launching a sun HotSpot JVM.

任何人都可以总结一下它的作用吗?

Can anybody sum-up what it does?

推荐答案

使用-server，JVM将更积极地编译热点(即，经常执行的部分代码)，因此，编译器将花费更多时间来进行编译.这样做.这不是问题，因为仅当进程运行较长时间(例如，在服务器上)时才使用此选项.

With -server the JVM will compile hotspots (i.e. parts of the code that are often executed) more aggressively, and as a consequence the compiler will take more time to do so. This is not a problem since you only use this option when your processes run for extended periods of time (e.g. on a server).

使用-client时，完成的优化更加轻松快捷，因为在运行客户端应用程序时，当编译器启动时，您不希望长时间停顿.

When using -client, the optimizations that are done are much lighter and quicker, because you don't want long pauzes when the compiler kicks in when running a client app.
