Java Platform Performance on Multicore: Better Performance or Bigger Headache?
TS-9363


Presenter: Azeem Jiva, AMD


Java technology-based applications are not easy to optimize, especially on multicore processors, with issues ranging from garbage collection and Java Virtual Machine (JVM) options to quality of generated Java code. Multiple cores should improve Java technology performance, but when performance doesn't materialize, developers are left wondering what's going on.

AMD CodeAnalyst Performance Analyzer allows developers using the Java programming language to correlate time-based profiles, event-based profiles, generated (JIT) code, and other hardware issues back to their original Java source code. This session discusses intelligent use of AMD CodeAnalyst Performance Analyzer to investigate ways of improving Java platform performance with multicore machines.

Highlights include hardware counters, thread investigations, the effects of changes on generated code, and investigating hot methods. By the end of the session, developers will have an understanding of how to improve the multicore-machine performance of their programs written in the Java programming language.
