NetBeans Profiler

The NetBeans Profiler is a tool for the monitoring of Java applications: It helps developers find

s and optimize speed. Formerly downloaded separately, it is integrated into the core IDE since version 6.0. The Profiler is based on a Sun Laboratories research project that was named JFluid. That research uncovered specific techniques that can be used to lower the overhead of profiling a Java application. One of those techniques is dynamic bytecode instrumentation, which is particularly useful for profiling large Java applications. Using dynamic bytecode instrumentation and additional algorithms, the NetBeans Profiler is able to obtain runtime information on applications that are too large or complex for other profilers. NetBeans also support Profiling Points that let you profile precise points of execution and measure execution time.
