You're welcome! Honestly, I was shooting from the hip with that statement about the DM42 firmware being faster. I haven't used it in a long time, but it felt like program editing was much faster there than on the C47 platform. I haven't done any heavy programming with DB48x that needed navigation around big programs.

I really don't have any complaints regarding speed on DB48x. I am curious about the DM32 hardware, though, and how that performs. My biggest complaint about the DM42 hardware is the very limited FAT filesystem size, but I don't think the DM32 improves on that at all.

The C47 project is still in active development and the code has not been optimized and also contains 'extra' stuff to accomodate debugging. Once the functionality is complete, the team is planning to remove the extra bloat and then fine-tune for better performance. Speed increase factors from 2-3 and most likelu more are expected.

You're right, the DM32 FAT is also 6MB, a limit of the hardware used.
