I found a good list of free tools here: http://java-source.net/open-source/profilers
Java1.5 includes System.nanoTime() which gives a much more accurate way to measure fine grain performance. The ones on that list that look most useful for CPU profiling are JFLuid/NetBeans Profiler, and InfraRED. There are also Eclipse plugins called TPTP and Colorer http://www.eclipse.org/tptp/platform/documents/tutorials/jvmti/Java_Applicat ion_Profiling_using_TPTP-v2.0.html http://eclipsecolorer.sourceforge.net/index_profiler.html Most people I know seem to use the commercial tool JProfiler, you can get a few days free eval license, and it costs a few hundred bucks, but seems to be worth it.
