Tune Puma for production Rails 8 — worker process count (CPUs × 1.5), thread count per worker (3-5 default), memory budget per worker, jemalloc, preload_app + fork-safe initializers, the Ruby 3+ YJIT enable, GIL implications for thread count, signal handling, restart strategies, MALLOC_ARENA_MAX. Use when the user mentions Puma config, workers, threads, jemalloc, memory bloat, copy-on-write, WEB_CONCURRENCY, RAILS_MAX_THREADS, MALLOC_ARENA_MAX, or asks how many workers / threads to run.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'puma-tuning-and-concurrency' ] || [ -L ~/.agents/skills/'puma-tuning-and-concurrency' ]; then echo 'A skill folder named puma-tuning-and-concurrency already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/MadBomber/experiments' "$d" && git -C "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/rails-skills/27-puma-tuning-and-concurrency' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/rails-skills/27-puma-tuning-and-concurrency' ~/.agents/skills/'puma-tuning-and-concurrency' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'puma-tuning-and-concurrency' ~/.claude/skills/'puma-tuning-and-concurrency' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
