My point was that if we look at Rails performance going up 10%, what does that mean for time spent in Ruby. I'd believe anything from a 15% to a 80% reduction of time spent in Ruby code
I wasn't trying to say that Ruby indeed is 80% faster, but that it's pretty much impossible to drive actual Ruby speed up from Rails numbers, since we don't know nearly enough about the Rails app
It is possible Ruby itself got accelerated a lot, okay, I am just not sure that's relevant since almost all Ruby usage is Rails.
