Evaluating Elixir / Phoenix for a web-scale, performance-critical application

I’ve read several times that for performance testing you should run the app in production mode.

MIX_ENV=prod mix compile.protocols
MIX_ENV=prod PORT=4001 elixir -pa _build/prod/consolidated -S mix phoenix.server

This is from the 0.7.2 docs so I’m not sure it’s all still needed, but might be worth a try.
