对我来说，问题是一个包含上千个文件的nodes_modules文件夹。我不得不把这个目录标为排除目录。

还请参阅可能的问题列表。

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。

我的具体情况是: 当我在调试模式下运行代码时，我有许多方法断点，这使得我的intelliJ很慢。

我的特殊情况(Mac)是我编辑信息。Plist使用Java 1.7*(不管什么原因)，它运行起来像一条狗。

改回1.6*，安装java 1.6，速度很快。

在我的例子中，GIT集成似乎导致编辑器在使用13时慢得令人沮丧。

在GIT集成开启的情况下，在输入大约30个字符后，用户界面会冻结一秒钟左右。它通常不长，但很烦人。

我使用的是GIT 1.7.8.0。运行于Windows 7 64，固态硬盘，12g内存，intel I7, 8个cpu。我尝试了各种方法，比如更新idea64.exe。vmoptions使用更多的内存，如-Xmx2400m和-XX:MaxPermSize=2400m， -XX:ParallelGCThreads=6，但这并没有解决问题。

git存储库是1.3 gb，包含65,000个文件。

我在新的git存储库中创建了一个新的“grails”项目，没有问题。我在现有的大型git存储库中创建了一个新的grails项目，intellij很慢。我通过打开项目设置对话框并删除git根来关闭git集成，问题就消失了。

我尝试通过13个UI禁用所有GIT后台操作，但没有什么不同。我还尝试了GIT内置模式和本机模式，没有什么不同。

在我的情况下，解决办法似乎是禁用GIT集成，直到我需要它，然后重新添加GIT根。如果其他人可以验证相同的问题，那么我们可能会将其报告为问题。
