关闭当前未使用的任何打开的项目。

尝试在开发过程中关闭自动发布模式。

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.

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。

又有一个解决方案 删除这两个文件夹中的所有文件

.metadata.plugins \ org.eclipse.core.resources.history .metadata.plugins \ org.eclipse.jdt.core

这是第一次帮助。但它仍然保持缓慢

增加你的内存到8 GB以上，并禁用自动构建项目。这对我很管用。

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。
