Their low memory doesn't permit running test_codec on most test files since test codec wants the full file in ram (you can basically only test upto 128kbit/s). But if someone tested gigabeatfx, it should give quite similar results since they have almost the same processor. I don't think the extra function call overhead caused by long calls are noticeable.
