Scaling Ruby with Actors, or How I Learned to Stop Worrying and Love Threads
summary
Argues that Ruby can scale with threads by using actor libraries and lock-free primitives rather than raw mutexes, demonstrates APIs: Celluloid (object‑oriented actors, one real thread per actor today), actor_rb (older, procedural) and Girl Friday (queue + worker pool for background jobs), cites 10 million counter benchmark: MRI 1.9 shows no thread speedup (4s single and five threads), JRuby shows 2s single vs 1s with five threads (2x on two cores), recommends STM and compare‑and‑swap atomics.
