FYI, the VisualVM-Sampler features are described at http://java.dzone.com/announcements/visualvm-12-great-java.

VisualVM contains a subset of NetBeans profiler features (so NetBeans profiler is NOT based on VisualVM, see http://blogs.sun.com/nbprofiler/entry/five_visualvm_myths_demystified).

NetBeans profiler supports profiling Java 5 & 6 applications both locally and remotely. If you profile a NetBeans project the profiling session is set up automatically and you'll get more accurate data with lower overhead.

FYI, VisualVM 1.2+ has a nice plugin VisualVM-Sampler implementing a sampling performance and memory profiler with zero setup and minimal overhead. It's very useful for quick detecting bottlenecks in your applications.

If you want to get the best from the VisualVM instrumentation profiler check out the Profiling With VisualVM article.
