ProDelphi.Net is a tool to measure the runtime of programs written in Delphi for .Net.The principle of source instrumenting, the sophisticated measurement correction algorithm and the granularity of 1 CPU-cycle guarantee a high measurement accuracy. Even very small or multiple nested functions are measured precisely. After profiling with ProDelphi.Net you know where the bottle neck is, not where it might be. Source instrumenting also ensures that idle times caused by certain Delphi- or Windows- API-functions (e.g. Sleep, MessageBox, WaitForSingleObject etc.) are automatically excluded from measurement. The extremly low measurement overhead guarantees even to measure time critical applications. The user friendly human interface makes the profiling process fast and easy, the sorting viewer enables the user to find the bottlenecks at first glance. With one mouse click the file with the measured method is opened in Delphi. The cursor is positioned at the beginning of the measured method. An optional call graph shows who called a procedure and who is called by it. Also how often this happened and what time was consumed when processing this path is displayed. This call graph makes a quick 'following the execution path' possible without searching in the sources.With printing measurement results the success of an optimization can be documented.
