**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'.

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。

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。

除了最新的软件(最新的Eclipse和Java)和更多的RAM，您可能还需要

删除不需要的插件(并非所有插件都需要Mylyn和Eclipse的J2EE版本) 不必要的验证器 禁用拼写检查 关闭Java编辑器中未使用的选项卡(是的，它有助于减少Eclipse负担) 关闭未使用的项目 禁用不需要的标签声明(SVN/CVS) 禁用自动建筑

谢谢你的提示。 上面提到的这些选择对我帮助很大:

窗口:

增加内存&关于我在eclipse.ini中更新的Java版本:

-Dosgi.requiredJavaVersion=1.6
-Xms512m
-Xmx512m
-XX:PermSize=512m
-XX:MaxPermSize=512M
-Xverify:none

此外，由于我们正在优化速度，因此将-Xms设置为与-Xmx相同的值将使JVM以允许使用的最大内存量启动。

Linux / Ubuntu:

使用

update-alternatives --config java

问题可能是java缓存，或者java临时文件。

打开窗口的控制面板，找到Java面板 单击“常规”页签的“设置”， 删除临时文件，并设置存储临时文件的磁盘空间 文件大小不超过10000MB。 重新启动eclipse。恢复所有验证器，您将看到IDE Eclipse的速度是正常的。
