Elixir: une potion pour mixer complexité et concurrence en temps réel
summary
Elixir on the BEAM is shown with concrete numbers and a working demo: GenServer processes, supervisors and Phoenix LiveView plus PubSub implement Conway’s Game of Life, deployed with mix release. Processes cost about 2KB each, spawning thousands instantly; a 64×64 grid runs ~12k messages/sec at 150MB and 3% CPU, 16k processes hits 40k msgs/sec at 11% CPU, and the system reaches 1–3 million messages/sec before the browser becomes the bottleneck.
