I too found B4PPC slow at first but then that causes you to rethink how you write your program
Try not to loop round more than is necessary.
Use the DoEvents keyword which can often help to display results on the screen whilst calculations are still being processed.
And of course, you can always ask for our help and we'll often do whatever we can.
If you want to speed up the device then search for registry tweaks.
I'm running WM5 and have tweaked the GLYPHCACHE and FATFS settings to give my X51
v a little boost.
