Well, sometimes the issue isn't so much throughput but latency. Like
you have some ultra high priority task that decides to block all
processing for like 100 ms and some buffer fill up and you miss one
packet ever few minutes. I have that kind of stuff all the time on a
USRP1. It's not a real time OS so it's always better IMHO to be able
to cope gracefully with theses little glitches.
And if you're app expects a continuous stream of data to maintain
alignement, filling with zero is easy enough.
Cheers,
Sylvain
