Hello all,
I tend to start up emacs and keep it running, with gnus, for days if not
weeks. Today, I checked out Emacs's memory usage (M-x memory-usage RET)
and found that I have a ~ *Gnus Backlog*~ buffer that is >70MB in
size. Not a real worry on most of my systems but I'm curious:
1. what function does this buffer have in gnus?
2. can this be pruned back (manually or otherwise)?
thank you,
eric

See gnus-keep-backlog.

Customize gnus-keep-backlog.

I think this should help:
gnus-keep-backlog is a variable defined in `gnus.el'.
Its value is 20
You can customize this variable.
Probably introduced at or before Emacs version 19.32.
Documentation:
If non-nil, Gnus will keep read articles for later re-retrieval.
If it is a number N, then Gnus will only keep the last N articles
read. If it is neither nil nor a number, Gnus will keep all read
articles. This is not a good idea.
Thatʼs definitely a doc-string written by Lars :-)
Thereʼs also:
gnus-backlog-shutdown is an interactive compiled Lisp function in
`gnus-bcklg.el'.
(gnus-backlog-shutdown)
Clear all backlog variables and buffers.
Robert
