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.

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。

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。

也试试这个，它会提高性能:

清理索引-{工作区 路径}.metadata.plugins \ org.eclipse.jdt。核心清理历史—— {工作区 路径}.metadata.plugins \ org.eclipse.core.resources.history

清理上述文件夹不会影响项目文件。

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

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。
