How- and its JIT compiler with dynamically-typed languages is ever, unlike with Java, a statically-typed language, the per- often lacking, lagging behind purpose-built language-specific formance of the JVM and its Just-In-Time (JIT) compiler JIT compilers. Making the JVM perform well with various with dynamically-typed languages lags behind purpose-built statically- and dynamically-typed languages clearly requires language-specific JIT compilers. In this paper, we aim to significant effort, not only in optimizing the JVM itself, but contribute to the understanding of the workloads imposed on also, more importantly, in optimizing the bytecode-emitting the JVM by dynamic languages. We use various metrics to language compiler, instead of just relying on the original JIT characterize the dynamic behavior of a variety of programs to gain performance [8]. This in turn requires that developers written in three dynamic languages (Clojure, Python, and of both the language compilers and the JVM understand the Ruby) executing on the JVM. We identify the differences characteristics of the JVM workloads produced by various with respect to Java, and briefly discuss their implications.
