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.

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。

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。

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。

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。

在Windows 8上。 打开控制面板。找到Windows Defender。进入设置 排除Spring/Eclipse和工作区所在的所有文件夹
