The article seems a little misleading. Using turbolinks won't make your site slower than not using turbolinks. Even the people in a café in Prague will enjoy improved speed over a full page load. The point of the article is that a JavaScript MVC framework could make your site even faster. Fair enough, but I fail to see how that's a flaw in turbolinks. By that logic it's pointless to make any speed improvements unless we write our backend in assembly.
