Altering a process priority is indispensable when you wish to change the behaviour of a running program on the system. Most of the times, when one wants a program to complete its processing faster, tuning its priority holds the key.

Under Linux, this can be accomplished by two ways – GUI & CLI. For this article, we will look at changing a process priority the GUI way. The CLI warrants a separate article.

Once you have the process running, simply open the “System Monitor”. Do note, I am under KDE for this demonstration. So the system monitor options may vary as per your desktop environment. However, the corresponding options should be self explanatory.

Process Priority GUI

Once in System Monitor, click on the “Process Table” tab for a summary of running processes on the system. Here identify your program. In my case, I wished to increase the priority of the Openshot process so it may process my video faster. So upon highlighting the Openshot Video Editor’s process in the table, I hit F8.You should now notice a similar window like one shown above. Here drag the sliders to the right for faster processing. You will be prompted for the root password as you do so. That’s all, the process should now conclude faster.
