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。

除了为内存使用配置eclipse.ini之外。我已经通过“启动和关闭选项”进行了配置。我的月食现在燃烧得很快。

确保使用Sun JVM运行Eclipse。

在Linux上，特别是Ubuntu上，默认安装Eclipse以使用开源的GCJ，而GCJ的性能要差得多。使用update-alternatives——config java切换到Sun JVM，可以大大提高Eclipse中的UI的快快性。

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。

努力配置您的构建路径。如果代码完成需要遍历整个项目文件夹，则会占用大量内存。

右键单击项目并选择首选项。 选择生成路径设置并删除项目文件夹。 然后只添加包含源代码和库代码的文件夹。

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.
