Profiler

NetBeans Profiler is a module to provide a full-featured profiling functionality for the NetBeans IDE. The profiling functions include CPU, memory and threads profiling as well as basic JVM monitoring, allowing developers to be more productive in solving memory or performance-related issues.

Another tool being developed for profiling purposes is an integration of Visual GC into NetBeans IDE. For more details see the Visual GC Integration Module homepage.
