It's the same problem. A streaming feed gets all its processing
done in a single block. Thus you can have several second to a
minute while innd spins around the list of channels. If a nnrp
get in at the wrong time, the user waits a *long* time.

Now, thing about what several seconds of latency *per transaction*
will do to a nonstreaming feed -- that's why streaming really
kills nonstreaming feeds.

For your feed that stays current, you should check the dup
numbers. Odds are that, if they had streaming feeds as well, most
articles from you were rejected as dups. In some situations, this
allows a nonstreaming feed to at least not overflow its batch
files....
