你有大的公羊吗?创建一个ramdisk，并把你的

JDK JVM Eclipse 工作空间

确保将更改保存回HDD或提交给VCS，以避免断电时数据丢失。

虽然与Eclipse没有直接关系:

如果你运行的是Windows 7(可能还有Windows Vista)，如果你的东西在默认的位置——你的主文件夹里，一定要禁用工作空间文件夹的文件索引。Windows默认会索引你主文件夹中的所有内容，这对你的工作空间来说是一种浪费。(右键单击资源管理器中的工作区文件夹，属性->高级。)

我给了它大量的内存(在启动它的命令中添加一个- xmx开关)，并尽量避免退出和重新启动它——我发现最严重的延迟是在启动时，所以给它大量的RAM可以让我在崩溃之前保持更长的时间。

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.

如果您使用Maven和ivy，请检查它们的控制台，以防它们在构建期间占用处理。我使用ivy，在此基础上，我有某些JAR文件(内部)更改为相同的版本，所以它必须一直锻炼来获取它们。

如果您在网络驱动器上定义了项目，那么在构建/读/写类型的过程中也会遇到延迟。

禁用/卸载你不需要的插件。 你不需要的近距离视角 关闭未使用的数据库连接

我已经禁用了Windows > Preferences > General中所有未使用的选项，它对性能有巨大的积极影响，eclipse在切换选项卡时仍然很慢，我不想增加内存，但在滚动时要快得多。谢谢你的提示。
