I’ve written a response to Fabio Akita’s article published 2 weeks ago comparing the performance of his Manga Downloadr implementations in Elixir, Crystal and Ruby.

I found it odd that the Ruby version would take 27s, about twice the time the Elixir version took (15s) to complete the same task as the application was mostly I/O bound. So, I wrote another Ruby implementation of the test mode to do the same but designed to perform well and got better numbers than the Elixir version.
