Analyzing and Optimizing High Memory and Disk I/O Consumption of InfluxDB 1.8 on a Production Server

This article investigates why an InfluxDB 1.8 instance on a 32‑core, 64 GB server consumes over 58 GB of resident memory and generates heavy disk I/O, examines Go runtime memory accounting, uses system tools such as top, pmap, pprof and iostat for diagnosis, and presents configuration and runtime tweaks that reduce memory pressure and I/O load.

Root Cause Analysis and Performance Optimization of InfluxDB 1.8 Memory and Disk I/O on a Production Server

The article investigates why an InfluxDB 1.8 instance on a 32‑core, 64 GB production server consumes over 95% memory and generates heavy disk I/O, analyzes runtime statistics, pprof data, and Go memory‑release behavior, and presents configuration and runtime tweaks that reduce memory usage to ~55% and I/O load to acceptable levels.
