Hadley's book, "Advanced R" has a specific performance related chapter[1]. As well as techniques to boost performance within R, there's a section on "Alternative R implementations," which says in part, "There are some exciting new implementations of R. While they all try to stick as closely as possible to the existing language definition, they improve speed by using ideas from modern interpreter design." Renjin is listed in this section. While I don't have direct experience of Renjin, or any other alternative R interpreters, I'm inclined to believe Hadley has and if he believes they improve speed, I'll take him at his word.
