If ALSA gets its part right, the resulting latency will
just depend on how the app uses the ALSA interface, as it
does for a normal ALSA device. If the app does so in the
same way as e.g. Jack's backend, there should not be any
additional latency at all.

If ALSA can make a low-latency interface on top of an
interrupt routine or thread that runs every period and
is triggered by the soundcard, then (as a Jack client)
it should be able to provide the same low-latency
interface on top of the process callback which just
looks like a soundcard interrupt handler in user space.
There is no essential difference between the two.
