**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'.

我给了它大量的内存(在启动它的命令中添加一个- xmx开关)，并尽量避免退出和重新启动它——我发现最严重的延迟是在启动时，所以给它大量的RAM可以让我在崩溃之前保持更长的时间。

可能有一些事情会延迟eclipse的启动和退出。其中一个类似于Windows中的lookalike。禁用窗口动画和禁用启动活动可以在一定程度上加快窗口速度

类似于在eclipse中，我们可以有同样的东西Windows->一般->首选项->外观->关闭一些装饰选项。这可能会起到一点提振作用，但可能不会产生太大影响。

在我看来，你可能已经创建的工作空间中的项目应该限制在一定的范围内，如果项目更多，应该创建一个新的工作空间。例如，当您尝试在服务器上运行单个项目时，与在同一服务器上运行多个项目相比，它所花费的时间更少

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。

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.

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。
