What is the memory overhead?
DELPHI On average around 170Kb for a running application – though this varies with the number of entries in the DLL buffer (120 bytes per entry – defaults to 120K). Most of the memory overhead is from the DLL and the memory mapped file – your applications EXE files will only be 3Kb larger, with each trace call adding around 20 bytes of code and data (the exact figure is determined by the length of the description.) COM I have absolutely no idea.
