二、本文可能是全互联网唯一能用的IDEA激活方法了

Idea有一个配置文件，可以设置内存大小，就像JVM内存中的堆大小和堆栈大小一样，可以设置。设置后，您的性能将得到提高。查看如何修改它。

让我们首先讨论要修改的idea.vmoptions文件的位置。据估计，不同平台的名称可能不同。MAC如下图所示：

我怎样才能找到这个地方？如果我只用Mac，我想我不会，但如果我是个老手，我会的，

Option+CMD+P在访问窗口中隐藏或显示路径栏

这是显示上图的路径，然后您可以像windows一样单击此位置。

这是idea第17版配置文件中的信息。默认设置非常简单，只有几个。

解释：

1.Xms128m，最小内存
2.Xmx750m，最大内存
3.保留代码缓存的大小
4.使用concmarksweepgc，将generation设置为concurrent collection

默认值太小，所以如果您使用idea运行一个更大的项目，您的计算机将像拖拉机一样嗡嗡作响。哎哟，我的新MacPro启动了一个多模块Maven项目，就像一辆拖拉机，开始响起来，这让我的同学笑我是否真的买了它。很尴尬。
