I noticed that info in Emacs 21.2, on my 200MHz PC, is a lot more responsive
than in Emacs 22.0.50. Am I getting anything extra for the longer wait?

Does it help to set Info-hide-note-references to nil?
Sincerely,

I can't see any difference. I haven't been very scientific and it probably
wouldn't be noticeable with a more powerful computer.

Can you profile info.el with elp.el and show here what were the
hotspots? That could give a clue about where to look for the reasons
for the slowdown.

There is no way of knowing the answer until we know what causes the
slowdown. Would you like to debug it and find out?

Do you see a difference with Info-fontify-maximum-menu-size set to 0?
Could you try this on a slow computer?

In Emacs started with -Q -D I see no slowdown at all. But with full
.emacs loaded and Emacs desktop restored I observe a noticeable
slowdown even on 1GHz PC, when visiting Info nodes with large menus.
So I also could look for the reasons for the slowdown.
I profiled info.el with elp.el and got the following results
for visiting the node (info "(elisp)Top") from the Directory node:

These results indicate that the main source of the slowdown is the
menu items fontification code in `Info-fontify-node', and it is caused
by a large amount of Info menu items needed to be processed.

Yes, it seems to be a lot quicker. However, Info-fontify-maximum-menu-size is
defined in Emacs 21.2, and is set to 100000.

It would be good to have a profile produced by elp.el for both
versions of Emacs on the same machine. Could you please try to do
that?

While I still don't understand where the slowdown actually comes from
(e.g. why do 1559 calls to put-text-property take 0.01s with -Q -D but then
take 5.46s with a loaded .emacs? Also more than half the elasped time is
unaccounted for in the profile of the pathological case), we can always try
and move some of Info-fontify-node into font-lock-keywords where jit-lock
should help us stay nice and responsive.

How many menu items were there, in the case where this took 18 seconds?

But the strange thing in all of this is that Juri seems to say that
there is no slowdown with Emacs started with -Q -D. Does the same
apply to you? If so, what in your .emacs could produce the slowdown?
In as far as Info itself is concerned, I can only think of
`Info-refill-paragraphs', but the customization does, of course, not
need to be directly related to Info.
Sincerely,
Luc.

Repeating the experiment I get similar results with (22.0.50):
emacs
emacs -Q
emacs -D
emacs -Q -D
except that these are twice as fast as my previously posted result and the
user experience varies (emacs -Q seemed slower than emacs -D). I'm not
familiar with elp, but I imagine that there is some skill in understanding
the results and in doing a control test.

Definitely worth trying. But before doing that I want to understand
why in `emacs -Q -D' this is faster.

633.
If each one took 1/30 of a second, that is absurdly slow.
I wonder if some regexp is badly written and looping.
