How do I limit CPU usage in Linux? To run cpulimit as a background process, use the –background or -b switch, freeing up the terminal. To specify the number of CPU cores present on the system, use the –cpu or -c flag (this is normally detected automatically). Rather than limit a process’s CPU usage, we can kill it with the –kill or -k option. There are at least three ways in which you can control how much CPU time a process gets: Use the nice command to manually lower the task's priority. Use the cpulimit command to repeatedly pause the process so that it doesn't exceed a certain limit. Use Linux's built-in control groups, a mechanism which tells the scheduler to limit the amount of.

For example, you can use CGROUPS to tell a process within a CGROUP to use let’s say 100ms out of every 1000ms (or .1s out of every 1s) of CPU time. First create a CGROUP with the following command: $ sudo cgcreate -g cpu: / cpulimit. NOTE: Here, cpulimit is the group name that controls the cpu usage. How Linux CPU usage time and percentage is calculated? sum all of the times found on that first line to get the total time. divide the fourth column (“idle”) by the total time, to get the fraction of time spent being idle. subtract the previous fraction from 1.0 to get the time spent being not idle. multiple by 100 to get a percentage.

Now, let us limit the CPU usage of this process using CPULimit tool. Say for example, we will limit this process by PID to 30% CPU. To do so, run: $ cpulimit -l 30 -p 2331 &. Here, "-l 30" flag limits the process to 30%. "-p 2331" is the PID of highcpu.sh. 1. If there are currently less than 10 processes running concurrently (and by running I mean really running, not just waiting for user input or disk I/O), then it is virtually guaranteed that one of them will have more than 10% of CPU. Otherwise the CPU would be virtually idling. If we want to limit the CPU to 50%, we will only use 8 threads and 4 cores.
