Simple, yes. The beauty of APIs in the Ruby world really opened my eyes. But performant is never really was. For instance: at the time of Sinatra's first release Wicket (Java) already existed and was much more performant.
This is no surprise, I think the OP was stating that it is performant compared to RoR.
RoR is dog slow. In other news - sky is blue. This is no surprise.

I think Sinatra is "performant enough for most" at best.
It is at best an inappropriate comparison.
The comparison with Wicket was purely on performance. As that is something that Ruby will most likely never fully catch up with.
