增加你的内存到8 GB以上，并禁用自动构建项目。这对我很管用。

如果您使用Maven和ivy，请检查它们的控制台，以防它们在构建期间占用处理。我使用ivy，在此基础上，我有某些JAR文件(内部)更改为相同的版本，所以它必须一直锻炼来获取它们。

如果您在网络驱动器上定义了项目，那么在构建/读/写类型的过程中也会遇到延迟。

禁用/卸载你不需要的插件。 你不需要的近距离视角 关闭未使用的数据库连接

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。

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

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.

Windows用户:

If you go to Task Manager, choose the eclipse application, and click on the little arrow next to it, you will usually just see one sub-process appear below "eclipse.exe". However, in my case, if you have multiple instances of "Java Platform SE Binary", then end all of them. For some reason, I had three of these running in the background, even though I wasn't currently running any projects. Nevertheless, this will boost performance back to the way it likely was when you first installed eclipse on your computer.

如果更改后您不能再运行项目，那么尝试重新启动eclipse。
