我已经禁用了Windows > Preferences > General中所有未使用的选项，它对性能有巨大的积极影响，eclipse在切换选项卡时仍然很慢，我不想增加内存，但在滚动时要快得多。谢谢你的提示。

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。

转到Windows ->首选项->验证，取消选中任何你不想要或不需要的验证器。

对于Eclipse 3.7，您使用Windows ->首选项->通用->启动和关机。

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.

努力配置您的构建路径。如果代码完成需要遍历整个项目文件夹，则会占用大量内存。

右键单击项目并选择首选项。 选择生成路径设置并删除项目文件夹。 然后只添加包含源代码和库代码的文件夹。
