在ivyDE解析单核消耗100%CPU后，我的Eclipse经常永远挂起，我需要在windows任务管理器上杀死它，重新启动并再次解析ivyDE（希望它不会再次挂起）我在Windows7上运行Eclipse。Java：1.8.0_25版本，带有-clean-vmargs-Xmx4g-Xms750m-XX:MaxPermSize=256m

我遇到了同样的问题，通过在启动期间将内存分配更改为Eclipse，我能够解决这个问题。我建议使用以下方法之一。
选项1：编辑eclipse.ini并更改以下参数。根据系统上可用的RAM内存增加此值
-Xms512m
-Xmx2048m
还要检查或审查安装的插件，这些插件对你没有用处，可以删除。这有助于提高性能（将减少Eclipse使用的内存）。
选项2：我发现Eclipse的Mar版本稍微慢一点。使用更稳定的开普勒或LUNA版本。
