JRuby, at least in my experience, has not yet delivered performance in line with my expectations of a JVM-hosted language.
In my opinion, performance is by a huge margin the chief reason I do not begin new projects on Ruby. I would rather defer performance tuning efforts and scale complexity until much later in projects' life, rather than immediately following launch when I have 100 concurrent users hitting the application.
