Abstract: A method, system, and computer program for providing runtime performance analysis in a visual programming environment. A performance data collection technique for visual programming is defined, which accounts for the specialized nature of visual programming, and the analysis is based on this collected data. The performance data is expressed in terms of elements familiar to the visual programmer, as opposed to using a source code approach. In a preferred embodiment, these elements comprise events, actions, connections, and attributes. The code implementing a visual program is instrumented according to this performance data collection technique, and performance information is gathered as the instrumented program executes. Preferably, the information gathered comprises execution counts and elapsed time per element.
