I am happy with the answer.
Actually my concern was to understand the minimum latency in the event that
one needed to get a complete record before displaying it. In my
application, anything under 0.25 seconds is OK, but I heard people on this
group with some really tight real-time latencies for NF training. I was
just snooping around for anything that would cause EDF to be unsuitable for
our purposes.
This is getting exciting. In my working life, such a process would take
about 4 months.
