Aggregating Performance Metrics

Java Virtual Machine (JVM) performance is multi-faceted. Not only are there different aspects of Java performance to consider, but workloads behave and affect a JVM differently depending on its characteristics in relation to these aspects. This thesis demonstrates a method to characterize Java workloads from a performance point of view. A system for aggregating measurements from said workloads, depending their characteristics and user preferences, to a single performance index is implemented and presented. Finally a set of tools were developed which enables the user to configure a specific index setup, explore the computed index structure as well as report it in various formats.
