Linux Performance Tuning - A Question of Balance

Linux Performance Tuning in 2026 – A Question of Balance (Part 1: Setup & Tools) Tired of outdated “magic sysctl” advice that doesn’t work anymore? In this no-BS series, I show what actually matters for tuning modern Linux (Devuan, Fedora, Arch) on real hardware in 2026. In Part 1 we: Bust common myths (“old PC + Linux = fast”, “zram = free RAM”, “2–3× speedup from tweaks”) Set realistic goals — why we tune, and why 2–3× is usually impossible Install & validate the only tools you really need (top, vmstat, mpstat, iostat, sar, stress-ng) Run first stress-ng baselines to see what “normal” looks like on fresh hardware Share 50+ years of hard-earned lessons (mainframes to Ryzen) No hype. No snake oil. Just real measurements, stories, and rules that survive testing. Next video: Reading vmstat, mpstat, iostat, sar like a pro. If you’ve ever chased “magic tweaks” that made things worse — drop your story in the comments. Like & subscribe for more tuning that respects reality over hype.
