I also tuned vmargs and stuff. But what really sped up Eclipse on Windows is the "proper" configuration of the anti-virus software. You have to disable the on-demand scanning of packed files. jar files, and many files related to java are packed with PKZIP algorithm to spare space. Because Eclipse uses tons of java files, an anti-virus attempts to individually unpack and scan every one of them. So for Windows platform: turn off the on-demand scanning of packed files, otherwise Eclipse will be unusably slow. Please keep in mind, that disabling this unfortunately makes your system weaker against attacks, most of the malware use packers.

你有大的公羊吗?创建一个ramdisk，并把你的

JDK JVM Eclipse 工作空间

确保将更改保存回HDD或提交给VCS，以避免断电时数据丢失。

使用标准插件加速Eclipse的唯一真正方法是为其提供更多内存，在某些情况下还可以访问更快的存储空间/碎片整理的硬盘驱动器。

除此之外，在性能方面可以做的不多:大多数标准插件都没有持续的运行时成本，即使Mylyn也相对较快。

升级到您机器上支持的最新JVM也会有所帮助。

有些人会降级到较旧的Eclipse版本以获得更好的性能。使用Eclipse经典版而不是官方发行版可能也有意义。

虽然与Eclipse没有直接关系:

如果你运行的是Windows 7(可能还有Windows Vista)，如果你的东西在默认的位置——你的主文件夹里，一定要禁用工作空间文件夹的文件索引。Windows默认会索引你主文件夹中的所有内容，这对你的工作空间来说是一种浪费。(右键单击资源管理器中的工作区文件夹，属性->高级。)

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。

                       **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

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'.
