Introduction
When using a computer, we often have multiple applications running at the same time. However, not all applications require the same level of resources from the CPU (Central Processing Unit). Some applications, such as video editing software or gaming programs, demand more processing power to ensure smooth performance. On the other hand, background applications, like file syncing or system updates, can run without impacting user experience.
This is where CPU prioritization comes into play. CPU prioritization allows you to allocate more processing power to foreground applications, which are the active applications that you are currently using. By doing so, you can ensure that these foreground apps run smoothly and respond quickly to user input, even under heavy load. In contrast, background applications will have lower priority and utilize fewer system resources, minimizing their impact on the performance of your foreground tasks.
Prioritizing foreground apps is especially important for users who frequently work with resource-intensive applications or engage in tasks that require real-time responsiveness. Whether you are a content creator, a gamer, or simply someone who values a seamless user experience, knowing how to set your CPU to prioritize foreground applications can significantly enhance your productivity and enjoyment while using your computer.
This guide will walk you through the steps of setting CPU prioritization for foreground applications on various operating systems, including Windows, MacOS, and Linux. By following these instructions, you’ll be able to optimize your computer’s performance and ensure that the applications you’re actively using receive the necessary resources they need to run efficiently. So, let’s get started and learn how to make the most out of your CPU by prioritizing foreground apps.
What is CPU prioritization?
CPU prioritization refers to the process of allocating processing resources within a computer’s CPU to different applications or tasks. The CPU is responsible for executing instructions and performing calculations for all running programs on a computer. However, not all applications require the same level of processing power. Some applications may be more demanding, while others may run efficiently even with limited resources.
With CPU prioritization, you can assign a specific level of importance to different applications or tasks running on your computer. By doing so, you can ensure that critical or foreground applications receive a higher portion of CPU resources, allowing them to perform tasks swiftly and respond to user input in real-time. On the other hand, less important or background applications will receive fewer resources, minimizing their impact on system performance.
The concept of CPU prioritization is particularly relevant in multitasking scenarios where you have multiple applications running concurrently. For example, let’s say you’re editing a high-resolution video using professional software, while also running a web browser with multiple tabs open in the background. Without CPU prioritization, the background processes of the web browser could consume significant CPU resources, resulting in a slower video rendering process and potential lag when interacting with the video editing software.
By setting CPU prioritization to give higher importance to the video editing software, you can ensure that it receives the necessary processing power to carry out its tasks efficiently, even when other applications are running simultaneously. This means that your foreground application will have quick response times, smoother performance, and overall improved usability.
CPU prioritization can be particularly beneficial for tasks that require real-time responsiveness, such as gaming, video editing, 3D rendering, and audio production. By allocating more resources to these foreground applications, you can minimize delays and latency, resulting in a more enjoyable and efficient user experience.
Now that we understand what CPU prioritization is and its significance in optimizing system performance, let’s explore how to set CPU to prioritize foreground apps in different operating systems.

How to set CPU to prioritize foreground apps in Linux
Linux provides a wealth of options and flexibility when it comes to setting CPU prioritization for foreground applications. With a combination of built-in utilities and system settings, you can optimize CPU performance and ensure smooth operation for your active tasks. Here’s how you can set CPU prioritization in Linux:
1. Use the ‘nice’ Command:
The ‘nice’ command in Linux allows you to adjust the priority of a specific process. By default, processes have a priority of 0, but you can assign higher or lower values to determine their importance. To prioritize a foreground application, open the terminal and use the ‘nice’ command followed by the process you want to run. For example, ‘nice -n -10 ./myapplication’ would set the process priority to -10, prioritizing it over other background tasks.
2. Utilize the ‘renice’ Command:
The ‘renice’ command is used to adjust the priority of running processes. To prioritize a foreground application, identify its process ID (PID) using the ‘top’ command or other system monitoring tools. Once you have the PID, you can use the ‘renice’ command followed by the priority level and the PID to change the process priority. For example, ‘renice -n -10 -p 1234’ would set the priority of the process with PID 1234 to -10.
3. Adjust CPU Affinity:
CPU affinity determines which CPU cores are used by specific processes. By adjusting CPU affinity, you can dedicate specific cores to foreground applications, improving their performance. The ‘taskset’ command in Linux allows you to set CPU affinity for a process. Open the terminal and use the ‘taskset’ command followed by the CPU core(s) and the process ID (PID). For example, ‘taskset -c 0,2 -p 1234’ would set the CPU affinity of the process with PID 1234 to cores 0 and 2.
4. Prioritize I/O Using ‘ionice’:
In addition to CPU prioritization, you can also prioritize I/O operations for foreground applications using the ‘ionice’ command. This ensures faster disk and network access, enhancing the overall performance of the application. The ‘ionice’ command is used similarly to the ‘nice’ and ‘renice’ commands, allowing you to specify the priority level and the process ID (PID). For example, ‘ionice -c 1 -n 0 -p 1234’ would set the I/O priority of the process with PID 1234 to real-time.
5. Enable Real-Time Scheduling:
Linux provides the capability for real-time scheduling, which can greatly prioritize foreground applications. By default, Linux schedules processes based on the Completely Fair Scheduler (CFS), but you can enable real-time scheduling for critical applications. This can be accomplished by modifying the scheduling policy and priority using the ‘chrt’ command. However, modifying the scheduler requires advanced knowledge and caution to avoid system instability. Research and consult official documentation or expert resources before making any changes.
With these methods and commands, you can effectively set CPU prioritization for foreground applications in Linux. Experiment with different techniques and monitor the impact on system performance to achieve the desired results. Remember to exercise caution when modifying process priorities and consult official documentation or expert advice when dealing with more advanced configurations.
