Using Hardware Performance Monitors to Understand the Behavior of Java Applications
Modern Java programs, such as middleware and application servers, include many complex software components. Improving the performance of these Java applications requires a better understanding of the interactions between the application, virtual machine, operating system, and architecture. Hardware performance monitors, which are available on most modern processors, provide facilities to obtain detailed performance measurements of long-running applications in real time. However, interpreting the data collected using hardware performance monitors is difficult because of the low-level nature of the data. We have developed a system, consisting of two components, to alleviate the difficulty of interpreting results obtained using hardware performance monitors. The first component is an enhanced VM that generates traces of hardware performance monitor values while executing Java programs. This enhanced VM generates a separate trace for each Java thread and CPU combination and thus provides ...
