All good points :)
I use all of (1) autoloading, (2) --daemon mode for most of my quick
editing sessions, (3) I keep trimming my configuration from stuff I have
not used for months, and (4) fire up 1-2 different instances besides the
background daemon process: one for Gnus-only stuff, and maybe another
one for IRC windows.
Another neat thing to do is install a light-weight clone like `mg' and
use that for very basic editing. I even went so far as to import mg in
my own copy of the FreeBSD src/ tree and attach it to the normal build
process, so my laptop's custom FreeBSD version now includes:
$ which mg
/usr/bin/mg
This way even when my full Emacs installation is not available (i.e. in
single user mode) I can use a lean and fast editor with very familiar
key bindings.
There are packages for `mg' and other mini clones of Emacs in the
package collection of most UNIX-like systems today, so installing one of
them is another thing that may be useful to consider.
