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。

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)。

我也遇到过类似的减速，这个修复只适用于使用Eclipse的C/ c++变体的情况。对于C/ c++，你可能想要禁用索引器，它以占用CPU而闻名。它相当于VS智能感知。 要禁用CDT索引器，请进入Window->Preferences，在C/ c++选项卡下选择indexer并取消选中启用索引器。

通过增加堆空间和更改垃圾收集器设置来加速Eclipse，我尝试了许多方法。

但就我的本地开发而言，我认为禁用JVM垃圾收集器最适合我。

Mylyn的自动补全功能工作起来没有问题，(未响应)部分已被显著地最小化。

下面是eclipse.ini文件的快照。

-vm
--C:\JAVA\jre\bin\server\jvm.dll
C:\JAVA8x64\jre\bin\server\jvm.dll
-vmargs
-Xnoclassgc
-Dosgi.requiredJavaVersion=1.6
-Xms256m
-Xmx1024m

我尝试过使用JDK 6和JDK 8，在这两种情况下，都注意到显著的加速。
