OK - thanks for doing that. Given the stats:
,----
| org-cycle 3 0.050032 0.0166773333
| org-cycle-internal-local 3 0.04951 0.0165033333
| org-optimize-window-after-visibility-change 2 0.0380670000 0.0190335000
| ...
`----
it seems clear that org-mode is not the culprit and, at 0.05s, any
improvements made there are going to be completely swamped by the real
time sink (maybe the display code if I understand things correctly.)
Also, presumably you are not complaining about the 50ms delay: that
would be almost unnoticeable. How long does it take for emacs to show
you the file?
Some questions:
How much memory do you have on your system? How much memory does emacs
consume? Is your disk active when emacs is taking forever?
On linux, I get the first with
sed 1q /proc/meminfo
and the second with
ps awlx | grep emacs
and look at the RSS field (field 8 in the output); e.g.
,----
| $ ps awlx | grep emacs
| 0 9772 11777 1 20 0 51284 32660 - R ? 1:02 /usr/local/bin/emacs
`----
shows me that emacs is consuming roughly 32Mb. I have 1Gb of memory on
the machine, so that's a comfortable fit (about 1/30 of available
memory: leaves just enough space for X and firefox :-) ). If your
numbers are closer, then maybe that's a problem: in particular, if your
disk goes wild while emacs is trying to do its thing, you are probably
swapping heavily and your performance will *really* be in the
toilet. The only solution is to buy more memory (assuming your machine
can handle it.)
I should say that I know very little about Darwin, so all of the above
is pure speculation. Parts of it may be applicable: you'd need to check
with an OSX expert for more details.
If there are no problems of the sort described above, I would ask in an
emacs forum about the performance of the display engine on Darwin: do
other people see the slowness? It would show up even without org
(although org make the situation marginally worse to be sure.) Given
the font-lock setting that Bernt dug up, it seems likely that if memory
is not the problem, the display engine is.
HTH,
Nick
