You've seen, from my reply to Matt, why my *Messages* buffer is more verbose
than yours. It's on purpose, just to be able to figure out more easily what's
going on. Though, I don't have yet...

Honestly, that would not change that much. Having to wait 92 seconds at
startup, or a long time just a few minutes later has the same impact for me.
And: don't try to make me stop using Org ;-))

The only fontification customs that I do are here:

The goal is to highlight words such as FIXME, WARNING, XXX, TODO in as many
files as possible.
For Org, a small custom (of the custom) is done in order not to catch all TODO
words: the TODO words in headlines (i.e., preceded by `* ') are *not*
highlighted.
They are well highlighted when found in other portions of (normal) text.
Other custom:
--8<---------------cut here---------------start------------->8---
;; highlight columns 78 to 80 in some modes
(when (try-require 'column-marker)
(dolist (hook '(emacs-lisp-mode-hook
cperl-mode-hook
shell-mode-hook
text-mode-hook
change-log-mode-hook
makefile-mode-hook
message-mode-hook
texinfo-mode-hook))
(add-hook hook (lambda ()
(interactive)
(column-marker-1 78)
(column-marker-2 79)
(column-marker-3 80))))
--8<---------------cut here---------------end--------------->8---
for getting markers in columns 78 to 80, showing me I'm good for a `M-q'...
I've done multiple tests, now:
- with none of the 2 above sets of customs
- with the 1st custom disabled, and the column-marker one enabled
- with both enabled
Times observed (in seconds):
| | no highlight | column marker only | all highlights |
|------+--------------+--------------------+----------------|
| | 63 | 82 | 91 |
| | 65 | 84 | 96 |
| | 76 | 100 | 130 |
|------+--------------+--------------------+----------------|
| mean | 68 | 89 | 106 |
(note that times are really not that stable, while I always launched Emacs in
the same conditions, without doing anything else during that time!)
So, the above 2 sets of customs have a real impact on the load time.
But I'm still unsure how I have to change all of the above snippets of code,
in order to keep the same functionality, but without the time delays when
Emacs starts up...

My .emacs file is there:
http://www.mygooglest.com/sva/emacs-init-sva.el
Though it's well documented, it's not a tiny one... But very well structured,
so quite easy to find stuff related to each other.
I'm always interested by any comment...
Best regards,
Seb
