还有一件事可以在Windows和Linux上加速Eclipse——将JVM放在RAM磁盘中。

对于Windows，您可以使用Qsoft的商用RAM磁盘驱动程序。

对于Linux，可以使用Internet上许多文章中描述的任何一种方法。重要的是要为RAM磁盘提供比JVM大小大10%的额外空间。

来看看。这真的很重要。

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。

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。

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。

                       **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'.

确保使用Sun JVM运行Eclipse。

在Linux上，特别是Ubuntu上，默认安装Eclipse以使用开源的GCJ，而GCJ的性能要差得多。使用update-alternatives——config java切换到Sun JVM，可以大大提高Eclipse中的UI的快快性。
