@pactox My guess is what you experienced was due to using a low powered VM on a busy host. Erlang (which Elixir is based on) is known to be very fast and can handle lots of traffic, much more so than most other languages, as it's multi-threaded and concurrent out of the box, and has been since the 1980's.

I would say with the right hardware it's performance is on par with, or perhaps exceeds anything written with Go, but it may not perform well on low-end VM's. On real hardware Erlang/Elixir is seriously fast.
