Might be because there are no Multiface II's around. Anyway,
here are numbers for a hdsp 9652 + Behringer ada8000 audio
loop, the hdsp has similar core specs down to the FPGA
architecture.

jackd with -p 64 -n 2
jdelay -> pcm_playback -> ada8000 -> pcm_capture -> jdelay

makes jdelay say 195.440 frames which is good for
   2 x 64 frames jack latency
 + 2 x 33.72 frames non-jack latency (in part hdsp's handling,
in part the ada8000's handling)

Can't take the ada8000 out of the picture because the hdsp has
no analog inputs, same "problem" with a digiface, I guess.
I'd appreciate the same measurement from a multiface owner.
