Abstract. Java is widely deployed on a variety of processor architectures. Consequently, an understanding of microarchitecture level Java performance is critical to optimize current systems and to aid design and development of future processor architectures for Java. Although this is facilitated by a rich set of processor performance counters featured on several contemporary processors, complex processor microarchitecture structures and their interactions make it diﬃcult to relate observed events to overall performance. This, coupled with the complexities associated with running Java over a virtual machine, further aggravates the situation. This paper explores and evaluates the eﬀectiveness of empirical modeling for Java workloads. Our models use statistical regression techniques to relate overall Java system performance to various observed microarchitecture events and their interactions. Multivariate adaptive regression splines eﬀectively capture non-linear and non-monotonic ass...
