This is useful to control batch jobs, when you don't want them to eat too much CPU. In any case, the percentage is the same of what you see when you run top. Of course there is no secret if you are a C developer, but I will try to explain to everyone. So stay tuned for a new version. We are thankful for your never ending support. Also, it is able to adapt itself to the overall system load, dynamically and quickly.

But it is much better if you run cpulimit as root, in order to have a higher priority and a more precise control. Flatron Flatron 7 7 silver badges 21 21 bronze badges.
Limit CPU Usage of a Process in Linux with CPULimit Tool
The goal of cpulimit is to prevent a process from running for more than a specified time ratio. We have successfully tested cppulimit cpulimit for limiting the CPU usage in Ubuntu S enthusiast, an upcoming Linux SysAdmin, web developer, and currently a content creator for TecMint who loves working with computers and strongly believes in sharing knowledge.
May 26, at 5: Submit it here to become an TecMint author. Now we can test cpulimit to see if it actually does what it is supposed to. Of course there is no secret if you are a C developer, but I will culimit to explain ubhntu everyone. For this, we will first check the CPU usage without cpulimit and then implement the cpulimit to evaluate the same.

However, these tools are still useful even in current Linux systems. Let test it as follows:. Get your subscription here. In practice, I start handbrake, pause it, get its PID with top e.
The code is still experimental, so let me know how it is. Now cpulimit does limit also the children of the specified process. Your piece helped me immensely when I found it! Your name can also be listed here.
Ubuntu Manpage: cpulimit -- limits the CPU usage of a process
To specify the number of CPU cores present on the system, use the --cpu or -c flag this is normally detected automatically. This is useful to control batch jobs, when you don't want them to eat too much cpu. This feature is only available to subscribers.
The --pid or -p option is used to specify the PID and --limit or -l is used to set a usage percentage for a process.
