ProDelphi is a highly accurate, commercial source code profiler specifically designed to measure the runtime performance of applications written in Delphi Object Pascal and Lazarus. Developed by Helmuth Adolph, it has been used in the industry since 1998 to pinpoint software bottlenecks and optimize execution speeds. Core Technology & Accuracy
Source Code Instrumentation: Unlike “sampling” profilers that take intermittent snapshots of code execution, ProDelphi physically inserts measurement hooks into your source code. This guarantees that every single targeted function or procedure call is captured.
1 CPU-Cycle Granularity: ProDelphi measures code execution down to a single CPU clock cycle. It converts these raw cycles into exact time units based on the processor’s speed, making it reliable for optimizing highly nested or time-critical procedures.
Overhead Correction: It uses a built-in calibration routine to adapt to your specific processor and memory speeds. This allows ProDelphi to subtract its own tracking footprint, keeping results accurate and unbloated.
Automatic Idle Filtering: It automatically detects and excludes idle times spent waiting on specific Windows or Delphi API calls (such as Sleep, MessageBox, or WaitForSingleObject), tracking only true active runtimes. Key Features
Framework Support: It profiles VCL, CLX, and Cross-Platform FMX (FireMonkey) application frameworks.
Dynamic Activation: You can selectively toggle profiling on or off through an interactive dialog window rather than manually hardcoding API start/stop calls.
Visual Diagnostics: Results are rendered via a built-in viewer that features call graphs, sorted runtime breakdown tables, history tracking, and diagrams to compare sequential optimizations.
Post-Mortem Debugging: In the event of an application crash or unhandled exception, ProDelphi can reconstruct the call stack to show exactly where the program failed. System & IDE Compatibility
