Developer uses Claude Code to tune an Ubuntu development laptop
Understand this story
Developer Jordan Dimov shared his record of using Claude Code (Opus) to troubleshoot and tune an Ubuntu development environment on a Dell Precision 3591: disk usage dropped from 90% to 25%, boot time was shortened from 2 minutes 10 seconds to 20 seconds, and SSD freezes that occurred 5 to 68 times per boot and lasted 30 seconds each were eliminated. Dimov said Claude Code completed most of the troubleshooting work, but it could not use sudo, so it provided commands and he executed them himself. The above data comes from his practice record.

Jordan Dimov describes using Claude Code to diagnose and fix performance problems on his Ubuntu Dell Precision 3591 laptop, including a 90%-full disk from retained Rust debug builds, 30-second SSD freezes caused by Intel VMD (fixed by switching BIOS storage mode from RAID On to AHCI/NVMe), and a GPU kept awake by a kernel flag. Postgres tuning, parallel test databases, and CPU affinity changes cut the full test run from 283 s to 198 s and commits from 0.58 ms to 0.04 ms. He also covers local models on the 6 GB GPU, a pgvector-based code search tool, and a log-digest script for agents.
