Benchmarking programming languages and web frameworks

Phoenix (Elixir)

Phoenix is a web development framework written in Elixir that implements the server-side MVC pattern. It is designed to be fast and efficient, leveraging the Erlang VM's capabilities for building concurrent and fault-tolerant applications. Phoenix excels at handling high-traffic applications and real-time communication through WebSockets.

This benchmark tests how fast a framework can perform concurrent HTTP requests, I/O operations, and JSON de/serialization.

Null Safety

YES

Memory Management

Garbage Collection

Elixir is a functional, concurrent programming language built on the Erlang VM created by José Valim in 2011. It combines Erlang's fault-tolerance and distributed capabilities with a Ruby-inspired syntax. Elixir features immutable data structures and actor-based concurrency through lightweight processes.
