This is a command-line utility intended for use in a build process or from the Delphi tools menu, whose purpose is to integrate debug information into an executable. The debug information format  is a compressed version of JCL‘s JDBG.

As of know, SamplingProfiler is the only published utility that understands this format, so you can use it either to reduce the size of the executables you deploy for profiling purposes, or if you do not want to deploy directly-readable debug information files.

Use it to know which units contribute the most to an executable’s size, which DFMs are the largest, which units you have dependencies on but barely use in your executable, or merely to know exactly what gets into your executable.

You can integrate it into the Delphi IDE via the Tools menu, see the MapFileStats page for more details or to the download page and see for yourself!
