Yes we have CPU usage of around 30-40% by mediaserver when playing back MP3 over Bluetooth. Note that we do SBC encoding in the mediaserver. What kind of numbers were you expecting? The cpu usage in the kernel side shouldn't be too bad. It just slaps on some L2CAP headers, and the uart transfer uses DMA.
