PHP, Python, Ruby, etc. successfully power some of the largest sites in the world. Some ridiculously large fraction of the top 500 sites are using WordPress alone. "Ruby on Rails performs so bad that your Intel Xeon becomes as useful as a 99 cent Walmart calculator using it, so comparison doesn't say anything" is completely silly. Rails, PHP, etc. can scale to some of the biggest sites on the Web. Sure, they're inefficient, but sometimes you want to trade performance for ergonomics.
