Description: A user slice is a cgroup (control group) that limits the resources available to user services in operating systems using Linux-based kernels. This mechanism allows for the management and restriction of resource usage such as CPU, memory, and device I/O by processes running in user space. User slices are essential for ensuring that applications and services do not consume more resources than they are allocated, which helps maintain system stability and overall performance. Additionally, user slices facilitate the implementation of security and isolation policies, allowing different users or applications to operate in a controlled and protected environment. In the context of init systems like systemd, user slices are used to organize and manage services efficiently, ensuring that each service runs within its defined resource limits, contributing to better system load handling and preventing conflicts between processes.
