I don't know if thats true. I've been working on Rails apps for over 10 years (some poorly written.) I worked on one particular Rails app for 7 years. I've also worked on Java, Go, Elixir, and Haskell codebases. I find that anytime we went "Slow" was because of decisions that were made around the data model, which can happen in any framework or language. The thing that I love about working in Ruby is Rubyists tend to write fantastic tests (which double as documentation of what ever business logic), and the culture around "convention over configuration." So even when we decided to port one of those Rails apps to Elixir/Phoenix, it wasn't an absolutely awful rewrite.
