    1111The base test had all auxiliary features disabled (usb, serial, optical, networking, drag and drop, clipboard sharing and so on).

    13 DPCs/ISRs would take in the region of 300-500 micro-seconds (idle), with frequent spikes to 5ms and in some cases taking as much as 40-50ms when under load.

    15 When the audio input was turned off the DPCs/ISRs would range between 100-350 microseconds, with spikes at 500 microseconds, and peaks of 5-10ms when under load.

    1717So it looks like the audio interrupts may need some tweaking, and the CPU clock-rates corrected - 1200MHz is a lot of cycles going down the drain. With that said, some general refractoring and code optimisation may also be due across the board.
