Abstract

Using the Java(*) Virtual Machine Profiling Interface (JVMPI) to instrument a Java program with all method entries and exits can cause excessive overhead. We describe a selective class instrumentation approach that can significantly reduce that overhead. This makes feasible a wide range of performance experiments to pinpoint performance problems.
