Yeah. I'm confused, too.

Anecdote: I help maintain a pretty slow Rails app. I recently did some data munging in Go against the MySQL database that backs the Rails app. The Go tool was so fast, I thought it hadn't worked. It was basically instant. Accomplishing the same goals with Rails would have been slower by a factor of 10 in my experience.

I know Ruby != Rails, but if I'm doing this sort of thing in Ruby, I'm generally doing it in Rails or with a lot of the gems that Rails uses, so it's a fair comparison for my uses.
