i would wager that floating-point is not its forté, but rather than
give you an opinion, what would be got a good float-performance
benchmark that i can run on it to give you some real figures? is
there a preferred stdout-style C app i can run that'll give us some
real figures?
also keep in mind its dual-processor; the second processor is 100%
free to run code as fast as it can, while processor-1 is doing the
linux thing .. so while floating-point performance may be abysmal,
fixed-point math on the second CPU may just be fine ..

i wouldn't put this in the class of 'high-performance hardware', but
more 'hardware worth squeezing every last bit of performance out of
it'.

i don't think JACK would be wise on this thing, though i could be
wrong .. its really designed to be a 'single-app running at a time'
platform, and so far supports SDL/SDL_mixer, though you can do raw
hardware i/o to the codec of course, and .. well .. there is the
matter of USB-Audio Gadget drivers, which would provide a path to
higher-power DAW upstream ..
