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。

禁用病毒扫描程序，或至少将任何病毒扫描程序配置为在读访问时不扫描JAR文件。

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.

Eclipse会延迟加载插件，大多数常见的插件， 比如Subclipse，如果你不使用它们，就不要做任何事情。 它们在运行时完全不会降低Eclipse的速度，而且它 不能帮你让他们失效。事实上，Mylyn被展示过 在正确使用Eclipse时减少内存占用。

我运行Eclipse时使用了大量的插件，但没有任何性能 罚点球。

Try disabling compiler settings that you perhaps don't need (e.g. the sub-options under "parameter is never read). Which version of Eclipse are you using? Older versions were known to be slow if you upgraded them over and over again, because they got their plug-ins folder inflated with duplicate plug-ins (with different versions). This is not a problem in version 3.4. Use working-sets. They work better than closing projects, particularly if you need to switch between sets of projects all the time.

使用-Xmx不仅需要增加内存 开关，这也是烫发的大小。我认为 在Eclipse 3.4中解决了这个问题。

在特殊情况下，性能差可能是由于损坏了h2或nwire数据库。有关更多信息，请阅读加速Eclipse PDT和nWire的五个技巧。

在我工作的地方，我们依赖虚拟机来运行Debian。出于测试目的，我已经在VM上安装了另一个Eclipse版本，但如果我运行的是另一个Eclipse版本，有时会产生冲突。有一个两个Eclipse版本共享的共享文件夹。有一次我不小心让Debian Eclipse安装在后台运行，结果导致数据库文件损坏。

                       **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'.
