使用renice命令(通过Procmon或者命令行)可以使得系统为给定的进程分配一个更高的或者更低的优先级。
Using the renice command (either through Procmon or from the command line) can cause the system to either assign a higher or lower priority to a given process.
nice命令还可以用来启动具有不同优先级的进程。
The nice command can also be used to start a process with a different priority.
