Deep Dive into Linux cgroup CPU Subsystem and Container CPU Bandwidth Control

This article explains how Linux cgroup’s CPU controller works, covering the creation of cgroups, the kernel structures involved, how CPU time limits are configured via cfs_period_us and cfs_quota_us, how processes are attached to cgroups, and the scheduling mechanisms that enforce bandwidth limits in containers.

Understanding Linux cgroups and Controlling Process CPU Usage

The article introduces Linux cgroups as a kernel feature for limiting resources, explains their terminology and functions, and demonstrates a hands‑on experiment that creates a CPU cgroup, sets cpu.cfs_quota_us to restrict a process to roughly 25 % CPU usage, confirming effective resource control.
