I am not sure about my answer, but I would like to share it with you: 1. mpg123 uses floating point which uses double processing power than fixed point 2. when you compile it on DMxxxx and run it, I guess it detects the generic code and not the optimizied one 3. I guess you need to look carefully at the options using the command mpg123 --longhelp to get more options, they might be useful
