How do I reduce high CPU usage in Linux?

Restricting Process CPU Usage Using nice, cpulimit, and cgroups

1. Use the nice command to manually lower the task’s priority.
2. Use the cpulimit command to repeatedly pause the process so that it doesn’t exceed a certain limit.
3. Use Linux’s built-in control groups, a mechanism which tells the scheduler to limit the amount of resources available to the process.
