Groovy Vs Python and Ruby - Performance

I just happened to come across this article and I found it really interesting. It was often thought that due to a lot of runtime dynamic invocations made by Groovy it would be a lot slower in comparison to other dynamic languages but after the reading article below Groovy aint that bad after all. In fact it does a pretty decent job!!!
