根据我的经验，IntelliJ版本13明显比12版本慢。有几种方法可以加快速度，比如增加intelliJ的VM选项。如。我正在使用一个maven项目，为此我将运行器和导入器选项增加到4GB。它让事情变得比以前快多了。

75s -> 10s intellij启动。我所做的就是从默认的32位exe切换到64位exe。

我注意到禁用许多插件确实有助于提高IntelliJ的速度。例如，我不是在开发Android应用程序。关闭与Android开发相关的插件可以加快加载时间，并使程序在我的机器上运行得更流畅。

我也遇到过类似的问题。 在这种情况下，它就是Subversion插件。(Mac Mavericks, SVN版本1.7.10) 一旦我禁用了这个IntelliJ就可以再次使用了。

从早期测试开始，我就一直在使用13，没有任何问题。也许是你的特定设置。也许您的项目随着时间的推移而增长，您最初给Idea的内存现在已经不够用了?尝试为Idea提供更多的内存:http://www.jetbrains.com/idea/webhelp/increasing-memory-heap.html(关于如何做到这一点的说明)。
