Evaluation of Control Structures for Dynamic Dispatch in Java


Dynamic dispatch, or late binding of function calls, is a salient feature of object-oriented programming languages like C++ and Java. It can be costly on deeply pipelined processors, because dynamic calls translate to hard to predict multi-way branch instructions, which are prone to causing pipeline bubbles. Several alternative implementation techniques have been designed in the past in order to perform dynamic dispatch without relying on these expensive branch instructions. Unfortunately it is difficult to compare the performance of these competing techniques, and the issue of which technique is best under what conditions still has no clear answer. In this study we aim to answer this question, by measuring the performance of four alternative control structures for dynamic dispatch on several execution environments, under a variety of precisely controlled execution conditions.
