+**Description**: It is often thought that using a statically typed languages compiled to native code is the only route to
+fast code, even if at expense of increased verbosity and/or complexity of source code.  Languages using a
+virtual machine are still disparagingly lumped with interpreted languages and labelled "scripting
+languages".  Java shows us that statically compiled languages targeting a virtual machine can be as fast as
+native code (by using just-in-time compilation techniques).  Dynamically types languages remained
+disparagingly lumped with interpreted languages and labelled "scripting languages".  Then came invokedynamic.\\
+\\
+Groovy (along with JRuby, Jython, Clojure) is a dynamically typed language running on the JVM.  This gives
+all the runtime meta-object protocol that is seen as both good and evil depending on who you are, and how
+you view Groovy and other such languages.  At the same time it admits of a just-in-time compiler. Can Groovy
+now compete with Java at runtime performance now that invokedynamic is an integral part of the JVM and
+compiler writers for Groovy and other dynamic languages have incorporated its use.\\
+\\
+Does the JIT enhanced JVM perfomance now challenge native code languages such as C, C++, D, Go. Are dynamic
+language now as fast as static ones. Will Kotlin and Ceylon change things?\\
+\\
+For this and other exciting microbenchmark comparisons, be at this session.\\
