(Note that if you're going to have indivdiual buffers over 2 GB, you need
large file support enabled.)

I don't think so (but I don't use CNFS).

Well, do you want all of your articles to cycle at the same rate?  If you
separate them, you can use storage.conf to put some articles in one and
some in another.  For example, you could put all articles over 50KB in a
separate cycbuff, so that no matter how many binaries you get, your text
articles won't be "pushed out" too quickly.

This is a configuration thing that you might want to think about.  If you
just want to keep the same configuration you have now but extend the cycle
time, put them all together.

Uh.  No.
