YouTube, No. 2, was still running Python 2.7 as of last year. Python and Ruby are basically the same performance wise. Instagram is also a Python app, AFAIK. Last year they contributed some memory efficiency improvements to CPython. Shopify is likely the largest RoR site at 80k requests per second but since it's served as tons of different domains it doesn't really count.

Twitter was (originally) also built on RoR. Not to mention GitHub is a rails app.

  It's also worth noting that Twitter's feature velocity fell off a cliff when they moved to Scala.

    Oh interesting, I hadn't noticed that pattern.

    I do think though there is a certain size companies like this reach where they go from innovative to being afraid to change anything lest the viral popularity goes away.

Stripe is also on Ruby. I think we should separate Ruby and Rails in performance comparison. Python and Ruby are definitely on the same scale. >Shopify is likely the largest RoR site at 80k requests per second but since it's served as tons of different domains it doesn't really count. And Different DB etc... Last time I said this I got massively downvoted for it. I think Github is possibly the largest RoR site out there.
