We have 4 sites feeding us full feeds, though one of them is down for
some reason (the admin went on vacation and things crashed right after.
D'oh), and we feed one site. Even if you're handling lots of feeds, it
just means more disk i/o. *shrug* The load goes up when nntpsend runs,
because it has to parse the out.going/* files, but the rest of the time,
things only bog down when you get lots of people reading news and it
eclipses the available ram.
if you find that maintaining multiple newsfeeds (in and out) causes
the load to be high ordinarily on your server, your money would probably
be better spent on another computer which was dedicated only to managing
your newsfeeds, which in turn fed the news machine which your users have
access to. *shrug* More complicated to maintain, but without fabulously
expensive hardware, there are a lot of limitations on I/O that you're
going to get with any computer system.
(Admittedly, buying a sparc 20 with several large RAIDs would
probably handle things much more elegantly, but consider the
price-performance, _and_ the exceptionally wasted processing power of the
sparc).
