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.

这篇文章如何快速使eclipse更快是非常有用的。我尝试了一些技巧，这是真的;它使我的Eclipse运行得更快。

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)

当限制打开标签的数量时(过去我经常打开30多个标签)，我的性能有了相当大的提高。您可以让Eclipse自动为您处理这个问题:

窗口->首选项->编辑器->自动关闭编辑器

8个打开的标签是>>符号出现之前的金额，所以我倾向于让它保持在8。

当打开更多选项卡时，最近最少访问的选项卡将被关闭。

->当所有编辑器都是脏的或固定的

如果它有未保存的修改，你可以提示保存和重用(标签将被关闭，一个新的将被打开在它的地方)。或者你可以打开一个新的编辑器，从而增加打开标签的数量(不显眼的选择)。

如果你想确保一些标签永远不会自动关闭，你可以钉住它们。点击大头针图标(工具栏中最右边的图标，以“大头针编辑器”为tooltiptext)。

禁用标签装饰可以获得另一种性能提升 (Windows ->首选项;概述->外观->标签装饰) 在启动时禁用未使用的功能 (Windows ->首选项;一般->启动和关闭)。

您还可以根据JVM选择不同的垃圾收集策略来获得额外的性能。

如果你厌倦了重启周期，你可以使用ZeroTurnaround的JavaRebel。这将缩短重启服务器/客户端的时间。

这个线程中的最佳实践是在ZeroTurnaround的免费Optimizer For Eclipse中实现的。

它有什么帮助?
