Remember all those line format specification variables?
gnus-group-line-format, and so
on. Now, Gnus will of course heed whatever these variables are, but,
unfortunately, changing them will mean a quite significant slow-down.
(The default values of these variables have byte-compiled functions
associated with them, while the user-generated versions do not, of
To help with this, you can run M-x gnus-compile after you've
fiddled around with the variables and feel that you're (kind of)
satisfied. This will result in the new specs being byte-compiled, and
you'll get top speed again. Gnus will save these compiled specs in the
.newsrc.eld' file. (User-defined functions aren't compiled by
this function, though---you should compile them yourself by sticking
them into the
.gnus.el file and byte-compiling that file.)
