Our documentation recommends the use of Thin, which is a single-threaded, evented web server. In theory, an evented server like Thin can process multiple concurrent requests, but doing this successfully depends on the code you write and the libraries you use. Rails, in fact, does not yet reliably support concurrent request handling. This leaves Rails developers unable to leverage the additional concurrency capabilities offered by the Cedar stack, unless they move to a concurrent web server like Puma or Unicorn. So, do/will they now recommend Puma/Unicorn over Thin?
