I´m using the Google Chrome debugging tools. There you can see the getTranslationLanguages request which is WAITING for 12 seconds. But, anyway, I don´t know the reason why.
Please let my attach the screenshot.

I have no idea about what can it be. I don´t see any blog, issue or post on internet related to this. It´s strange this is only happening to me.
Anyway, remember the issue is not happening when I replace Unicorn with webRick.

   I'm using the Google Chrome debugging tools. There you can see the
   getTranslationLanguages request which is WAITING for 12 seconds. But,
   anyway, I don't know the reason why.
