Hell, Ruby is that slow?!

• prh8 3y ago
  It's not specifically Ruby, but also using ActiveRecord, loading bloated models, associations, and some business logic. There is also a large amount of memory bloat with the sitemap library when working with large datasets. The Crystal sitemap library has a way to avoid that same bloat. With Crystal, all of those things are massively faster.

  Since a library is mentioned, it is possible that the Ruby library was particularly inefficient compared to Crystal. Crystal is definitely faster than Ruby, but I expect differences to diminish in IO-bound operations (which sitemap generation sounds like it would be).

    Crystal supports directly interacting with the IO streams, so even if it is IO-bound it still can be a lot faster.

      What does Crystal's IO stream support provide that Ruby's does not? Both expose very similar IO stream interfaces from my experience.
