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。

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。

在eclipse.ini文件中添加-Xverify:none。

它将大大缩短Eclipse启动时间(对我来说是50%，如果不是更多的话)。这将告诉VM不要验证它正在加载的所有.class文件。

考虑一下:永远不要在生产系统中禁用字节码验证 (如评论所述)

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.

好吧，如果您正在使用Eclipse开发GWT应用程序，那么方法如下:

Eclipse中的内存不足错误

还记得将相同的VM参数添加到托管模式配置中。

也试试这个，它会提高性能:

清理索引-{工作区 路径}.metadata.plugins \ org.eclipse.jdt。核心清理历史—— {工作区 路径}.metadata.plugins \ org.eclipse.core.resources.history

清理上述文件夹不会影响项目文件。
