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.

Limiting CPU Usage of a Third‑Party SDK with cgroup and cpuset on Linux

This article demonstrates how to accurately measure and restrict the CPU consumption of a CPU‑intensive third‑party SDK by creating and configuring cgroup and cpuset groups, binding the process to a single core, and verifying the limits with stress testing tools.
