How to Fix CPU0 Overload on Multi‑Core Web Servers Using taskset and PHP‑FPM

This article shows how to detect a CPU0 load imbalance on a multi‑core web server, confirms PHP‑FPM as the cause with mpstat and pidstat, and provides a Bash script that uses taskset to evenly distribute PHP‑FPM processes across all CPUs, plus a cron tip to keep the setting persistent.
