" summary

A live demo builds an address-book app with 50 seeded users and benchmarks Rails vs Phoenix (Elixir/Erlang). Measured latencies: Rails ~1265 ms first load then ~100 ms on repeats, Phoenix ~120 ms then ~20–30 ms; Phoenix remains much faster for uncached reads and writes and claims support for millions of concurrent users on one server. The demo uses scaffold, Faker, MySQL, caching and delete benchmarks to validate performance and shows Rails can appear faster only with aggressive caching at the cost of stale pages when other processes mutate the database.
