The Journey of Optimization

A deep dive into optimizing Elixir’s Calendar module, improving datetime serialization performance through iodata and improper lists

Recently, I watched some Elixir vs Go comparison videos on YouTube. After the first comparison, José Valim made a PR to make the comparison more accurate. One key difference was that the Elixir version used Ecto and serialized datetime multiple times, while the Go version used raw SQL and single datetime serialization.
