Article Backlog
===============

   If you have a slow connection, but the idea of using caching seems
unappealing to you (and it is, really), you can help the situation some
by switching on the "backlog".  This is where Gnus will buffer already
read articles so that it doesn't have to re-fetch articles you've
already read.  This only helps if you are in the habit of re-selecting
articles you've recently read, of course.  If you never do that,
turning the backlog on will slow Gnus down a little bit, and increase
memory usage some.

   If you set `gnus-keep-backlog' to a number N, Gnus will store at
most N old articles in a buffer for later re-fetching.  If this
variable is non-`nil' and is not a number, Gnus will store _all_ read
articles, which means that your Emacs will grow without bound before
exploding and taking your machine down with you.  I put that in there
just to keep y'all on your toes.

   This variable is `nil' by default.
