Question

症状：

点击下拉列表，其下的所有选项列表显示
所有其他UI元素都是交互式的;没有明显的延迟
只用14毫秒来ping我正在进入的主机

如何加快下拉列表的响应速度？

我跑的命令：

ping <destination host>
PING <destination host> (<destination ip>) 56(84) bytes of data.
64 bytes from <destination host> (<destination ip>): icmp_seq=1 ttl=50 time=16.4 ms


ssh -X <destination host>
java -cp <class path stuff> <class with main method that initializes the UI>

我找到了一个临时解决方案。我有两台显示器（笔记本电脑和外接显示器）。我禁用了笔记本电脑显示器，现在运行顺畅。此解决方案基于以下帖子：Workaround for Slow Java Swing Menus。
