Yes, it can. Specifically, fontifying tags can be costly. For
illustration, below if profiler report for a very large agenda buffer
(1468 entries):
19820 95% - org-agenda
...
4401 21% - org-agenda-fix-displayed-tags
3711 17% + org-mode
...
1410 6% - org-buffer-substring-fontified
1380 6% + jit-lock-fontify-now
(full profiler report at the end of the message)
The total slowdown is ~30%, though the second part will only be slow
before the headings are fontified first time by
org-buffer-substring-fontified. Subsequent agenda rebuilds will be
faster.
The first part is harder. It is related to tag fontification. Currently,
agenda fetches tag list as unfontified strings via org-get-tags. So, I
had to re-fontify tags manual is temporary org-mode buffer. You can see
that running org-mode in fresh buffer takes a lot of time. Alternative
approach would be modifying org-get-tags to return fontified strings,
but I am not sure if it is safe to do - unrelated parts of org
might be affected. Or I can write something like org-get-tags-fontified.
What do you think?
Best,
Ihor
