OS Fundamentals - how greedy are your processes? | Linux niceness

Discovering Backend Bottlenecks: Unlocking Peak Performance https://performance.husseinnasser.com In this video I explain linux Nice processes and how to change the priority of a process. In the Linux operating system, processes manage and execute applications and tasks. One of the key utilities for managing processes on Linux is the `nice` command, which adjusts the priority of a process. Every process on Linux is assigned a 'niceness' value, which ranges from -20 (highest priority) to 19 (lowest priority). The default niceness value for processes is 0. By adjusting this value, users can influence the scheduler's decisions, giving more CPU time to crucial tasks and less to background jobs. The related command, `renice`, allows users to modify the priority of an already running process. Both utilities, when used correctly, provide users with fine-grained control over system resources, ensuring that the system remains responsive and efficient in multitasking environments.
