This guide explains how to analyze and troubleshoot situations where a Linux system shows high load averages despite low CPU usage, covering common load analysis methods, key commands like top, vmstat, iostat, and practical solutions for I/O bottlenecks and stuck processes.
This article explains Laravel's Eloquent ORM relationship loading methods, comparing the eager-loading `with` function and the lazy-loading `load` function, detailing their mechanisms, advantages, cautions, appropriate use cases, and providing practical code examples for backend developers.
This guide explains how to analyze Linux load situations—whether CPU and load are both high or CPU is low while load remains high—by using commands like top, vmstat, iostat, sar, and jstack, and provides practical troubleshooting steps for common I/O‑related issues.
This guide explains how to analyze and troubleshoot situations where Linux systems show high load averages despite low CPU usage, covering common load analysis methods, key commands like top, vmstat, iostat, sar, and ps, and practical solutions for I/O bottlenecks and D‑state processes.
The article explains CPU utilization and CPU load, clarifies time‑slice concepts, distinguishes user‑mode and system‑mode usage, describes how load reflects the average number of runnable and waiting tasks, and provides Linux commands and troubleshooting steps for high‑load/low‑utilization and vice‑versa scenarios.
This article explains the difference between CPU utilization and CPU load, describes how to interpret these metrics, and provides practical Linux commands and step‑by‑step methods for diagnosing high load with low utilization or vice versa, including common I/O and indexing issues.
