I sometimes think the hunt for super-low latency is a bit absurd! 3ms,
to give you a 6ms round trip, should be a workable amount for pretty

many working methods require the full round trip!)
I think that might be explained by "hidden" hardware latency, e.g my
multiface has 32 frames of hardware buffering, and then the ada
conversion takes another 15/16 frames. In effect meaning that apart
from the latency set in jack, there is another 95 frames of latency
going from analog input to output.
Other hardware can add a lot more "hidden" latency, and so do the
usb/fw bus. This can be checked relatively easily with a loopback test.
Yeah there will always be some processing/propagation delay. Too often I
swear you just hear people hunting after figure and not even realising
once they get the a point the hardware delays are actually going to be
larger than the software delays and it's a world of diminishing returns...
