I'm sending you the link to the video, so you can watch the performance.
But... how does your demonstration prove anything about Pascal/FPC ? libXMP is written in C and it is reasonable to presume that, it is that library that is mostly, if not entirely, responsible for the performance.
Can you make a demo like the one in your video using _pure_ Pascal/FPC ?
Also, if you give credit to the language used, in this case Pascal, then it seems reasonable that you provide the source code for the results to be verified by others.
