Depends on what you mean by "partial feed".  If your C-news takes over an
hour to unpack even a full feed, something's busted.  Are you using dbz?
My 3b1 with B-news probably takes about 10-15 minutes per day to unpack my
entire feed - perhaps about 1Mb compressed daily. On the other hand, C-news
could do the whole thing in under a minute.  I maintain both types of news systems,
so I have a pretty good idea of how both behave.

Sigh.... Making Kermit run setuid (fixing some of the security holes that
may open) is a better solution.

That's what I meant.

Pretty well.  I don't let other people log into it and I'm running other
software to confirm and maintain security and detect security breaches.
