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)。

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。

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。

                       **Tips for making Eclipse IDE Faster**

Eclipse在处理小型项目时运行得更快。但是当你不得不处理一个大项目时，你会对它的速度感到恼火。即使有一个巨大的RAM，你也不会满意它 速度。以下步骤将帮助eclipse提高其速度

Remove unwanted activation of some of the plugins at start-up by going to windows–>preference–>General–>Startup and shutdown also make sure you don’t use those plugins in any of your views Disabling label decorations which is of less use for you, will also help you to gain some performance . Go to Windows–>Preference–>General–>Appearance–>Label -> Decorations Close unwanted projects and use working set option to move from one group of project to another smoothly. Configure eclipse.ini which will be available in the eclipse installed location.

   Configuring eclipse.ini should be based on your RAM
   -Xms256m
   -Xmx512m
   -XX:PermSize=512m
   -XX:MaxPermSize=512M

也可以访问http://wiki.eclipse.org/Eclipse.ini获取更多选择 配置eclipse.ini。

Do not keep lot of tabs opened in the editor. Better to have around 20 tabs . Regularly close the unused tabs. To open resource we can always use ctrl+shift+R and ctrl+shift+T (java resource) instead of opening lot of tabs I experienced a considerable improvement in performance when limiting the number of open tabs (In the past I frequently had 30+ tabs open). You can let eclipse handle this for you automatically: Window->Preferences->Editors-> close editors automatically 8 open tabs is the amount before the >> sign appears, so I set 14 as my default value. When opening more tabs, the ones the least recently accessed will be closed. When all editors are dirty or pinned. If it has unsaved modifications you can prompt to save & reuse (tab will be closed, a new one will be opened in its place). Or you can open a new editor end thus increase the amount of open tabs (the unobtrusive choice). If you want to ensure some tabs never get closed autmatically, you can pin them. This by clicking on the pin icon (the rightmost icon in the toolbar, with “pin editor” as tooltiptext). Go to Windows -> Preferences -> Validation and uncheck any validators you don’t want or need. Go to Windows -> Preferences -> General -> Appearance -> and uncheck any animation you don’t want or need. Go to Windows -> Preferences -> Maven and check 'do not automatically update dependencies'.

另一个技巧是禁用自动构建。

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。
