Another item that helps me, apart from replacing OpenJDK with SunJDK is the "Scanning Sources" which can be disabled if you goto Tools -> Options -> Misc -> Files and uncheck the Enable "auto-scanning" of sources.
I am not 100% sure what that option does, but it speeds up my projects. Also I would try NetBeans 7, they have made massive leaps and bounds in the newer versions from the older (not knowing what version you are using).

除了用 SunJDK 替换 OpenJDK 之外，另一个对我有帮助的项目是“扫描源”，如果您转到“工具”->“扫描源”，则可以禁用它。选项->杂项 ->文件并取消选中启用源的“自动扫描”。
我不能 100% 确定该选项的作用，但它可以加快我的项目速度。另外，我会尝试 NetBeans 7，它们在新版本中较旧版本取得了巨大的飞跃（不知道您使用的是什么版本）。

是的，众所周知，Netbeans 在使用 OpenJDK 时运行速度较慢。
