It depends on the metrics you care about. Ruby is concise compared to Go though. I like Go and but when I use it I have to accept that I'll write (and debug) at twice as much code as I would do in Ruby. If you're mostly just loading data into a large fast cache, lines of code may be a more critical dimension than execution speed. That's how well designed Rails projects work and you get most of what you need straight out of the box.
