mw-pfeddersheim-workstation Performance Tuning

Overview

This document tracks optimization decisions, system tuning parameters, and cleanup routines implemented for the workstation to ensure maximum resource efficiency and stability.

Current System State (2026-02-27)

• CPU: AMD/Intel (High core count assumed from load distribution)
• RAM: 64GB
• Storage: NVMe (77% usage detected)
• OS: CachyOS/Arch Linux

Optimization Strategies

1. Kernel Parameter Tuning (Ansible)

• vm.swappiness: Set to 10 to prefer RAM over swap on the 64GB machine.
• fs.inotify.max_user_watches: Increase to 524288 for IDEs and build tools.
• vm.vfs_cache_pressure: Set to 50 to improve filesystem cache retention.

2. Storage & Filesystem Cleanup

• Docker: Automated pruning of unused images and volumes via scripts/maintenance.sh.
• Journald: Vacuuming logs older than 7 days or exceeding 500MB.
• Package Manager: Maintaining only the last 2 versions of packages in the cache.

3. Service Optimization

• Ananicy: (Optional) Use Ananicy-cpp for automatic process prioritizing (CachyOS default usually).
