Just curious, what makes Crystal so much faster for this use case?

  Crystal performance is close to Go-lang. It's just very fast across the board. Consequently, just like Go-lang, it beats Ruby by an order of magnitude on pretty much any benchmark. Newcomers often assume Crystal must be sluggish like Ruby because "how could a language with such a convenient syntax be so fast", but it really is not. https://www.techempower.com/benchmarks/ https://www.techempower.com/benchmarks/

      in fact Crystal concurrency is the same with Go, both using coroutine technique. though Go should be more performance because it is built for that feature.

        Interesting, I might give Crystal a try!

  The biggest thing is the massive speed improvement compared to working with bloated ActiveRecord models, associations, plus some memory bloat. The Crystal implementation is massively fast dealing with database data.
