How to Diagnose a 100% CPU Spike in 3 Minutes: From Symptom to Root Cause

When a production service shows 100% CPU usage, this guide walks you through a rapid three‑minute workflow—identifying the affected scope, distinguishing user, system, iowait, steal and softirq metrics, and using Linux, systemd, Docker/Kubernetes and language‑specific tools to pinpoint the offending process, thread, or system call before taking corrective actions such as throttling, scaling, or rolling back.

How to Choose Between LVS, Nginx, and HAProxy: A Practical Performance Comparison

This article presents a systematic, non‑prescriptive methodology for evaluating LVS, Nginx, and HAProxy—including traffic‑path analysis, environment preparation, identical backend setup, scripted load tests, multi‑stage measurement (warm‑up, steady‑state, fault injection, recovery), and decision criteria such as layer requirements, health‑check semantics, connection limits, observability, and operational risk.

MySQL Replication Lag Soars to 10 seconds? Three Parallel‑Replication Tricks to Fix It

When MySQL replication latency jumps from milliseconds to 10 seconds, blindly raising replica_parallel_workers won’t help; the article walks through diagnosing the delay, then applies three concrete parallel‑replication optimizations—enabling WRITESET on the source, configuring LOGICAL_CLOCK with appropriate applier workers, and optionally preserving commit order—while showing the required SQL commands, monitoring queries, and rollback steps.
