如果Eclipse运行缓慢，我遵循以下几个步骤:

Any unused plugins installed in Eclipse, should uninstall them. -- Few plugins makes a lot much weight to Eclipse. Open current working project and close the remaining project. If there is any any dependency among them, just open while running. If all are Maven projects, then with miner local change in pom files, you can make them individual projects also. If you are working on independent projects, then always work on any one project in a workspace. Don't keep multiple projects in single workspace. Change the type filters. It facilitates to specify particular packages to refer always. As per my experience, don't change memory JVM parameters. It causes a lot of unknown issues except when you have sound knowledge of JVM parameters. Un-check auto build always. Particulary, Maven project's auto build is useless. Close all the files opened, just open current working files. Use Go Into Work sets. Instead of complete workbench. Most of the components of your application you can implement and test in standalone also. Learn how to run in standalone without need of server deploy, this makes your work simple and fast. -- Recently, I worked on hibernate entities for my project, two days, I did on server. i.e. I changed in entities and again build and deployed on the server, it killing it all my time. So, then I created a simple JPA standalone application, and I completed my work very fast.

Eclipse会延迟加载插件，大多数常见的插件， 比如Subclipse，如果你不使用它们，就不要做任何事情。 它们在运行时完全不会降低Eclipse的速度，而且它 不能帮你让他们失效。事实上，Mylyn被展示过 在正确使用Eclipse时减少内存占用。

我运行Eclipse时使用了大量的插件，但没有任何性能 罚点球。

Try disabling compiler settings that you perhaps don't need (e.g. the sub-options under "parameter is never read). Which version of Eclipse are you using? Older versions were known to be slow if you upgraded them over and over again, because they got their plug-ins folder inflated with duplicate plug-ins (with different versions). This is not a problem in version 3.4. Use working-sets. They work better than closing projects, particularly if you need to switch between sets of projects all the time.

使用-Xmx不仅需要增加内存 开关，这也是烫发的大小。我认为 在Eclipse 3.4中解决了这个问题。

在特殊情况下，性能差可能是由于损坏了h2或nwire数据库。有关更多信息，请阅读加速Eclipse PDT和nWire的五个技巧。

在我工作的地方，我们依赖虚拟机来运行Debian。出于测试目的，我已经在VM上安装了另一个Eclipse版本，但如果我运行的是另一个Eclipse版本，有时会产生冲突。有一个两个Eclipse版本共享的共享文件夹。有一次我不小心让Debian Eclipse安装在后台运行，结果导致数据库文件损坏。

问题可能是java缓存，或者java临时文件。

打开窗口的控制面板，找到Java面板 单击“常规”页签的“设置”， 删除临时文件，并设置存储临时文件的磁盘空间 文件大小不超过10000MB。 重新启动eclipse。恢复所有验证器，您将看到IDE Eclipse的速度是正常的。

我实现了一个插件来配置在运行时加载哪些特性，以提高性能并减少不同插件之间的冲突。

您可能已经在Eclipse中安装了许多特性，例如Android开发工具、C/ c++开发工具、PHP、SVN、Git和ClearCase插件。因此Eclipse很重，需要消耗大量内存，其中一些并不经常使用。

因此，您可以使用我的工具创建不同的运行时策略，例如一个包含Android、Git和基本Eclipse，另一个包含C/ c++、SVN和基本Eclipse。下一次，如果您使用的策略只有Android和Git, Eclipse将只加载指定的特性。

欢迎您试用并反馈给我。：）

该工具的名称是Equinox Advanced Configurator。
