Re: [O] Ridiculously long (2 minutes) startup time for org agenda

[JI Xiang]

I finally found out the problem. I've been using Spacemacs and the 
`spell-checking` layer would automatically initiate flyspell on each org 
file, resulting in tremendous delay. If I disable flyspell from being 
automatically activated, the agenda is shown in a few seconds.

It can be many things. My emacs was taking 6 minutes to open for some 
years, due to many reasons: a slow computer, many org files and very 
large (>100 files, >25 Mb in total), lack of optimizations from my 
side and from org-mode's side. I got used to it but it's a very bad 
experience, specially when it crashes (and I made it crash a lot).
Now org-mode has improved and I disabled the slow parts, and it opens 
very fast (<20 seconds). I still open large files.


The problem may not only be in org but in emacs (e.g. vc-mode can be 
slow), though from the instrumentation you send, it doesn't seem to be 
the case because it doesn't spend time opening the files.


org-agenda-prepare-buffers is the slow function, so it's the one you 
should check. Try to use edebug in it (C-u M-C-x) and run it slowly to 
see in which section it's the slowest. Then optimize that part. You'll 
see many optimization there (ignore properties, etc.). I had to 
disable many slow things, like <<>> (when you use a lot, e.g. 
1000 per file, it's too slow and even crashes), I think that these 
radio targets were the main reason of the slowness.


Try creating a very large file and then check opening it, to see if 
it's also slow.
Try things in a clean emacs (e.g. starting with: emacs -Q), because 
you may have some other mode enabled that wants to do lots of things 
when you open the files.


You can test many more things. But keep testing, because it's possible 
to make it work faster.

[O] Ridiculously long (2 minutes) startup time for org agenda

[JI Xiang]

Hello, first time posting on the mailing list. I encountered a problem 
where my agenda view (`C-c a a`) is taking ridiculously long (nearly 2 
minutes) to be shown the first time. From the second time onwards, the 
time is about 11 seconds, which is still very long by any means.


I wondered whether it has something to do with me having many files in 
the agenda list, so I tried to restrict the list to just one file. But 
still the first call to org-agenda-list took 12 seconds. This shouldn't 
be normal, right?


The following are shown in the `Messages` buffer during the call.

Re: [O] org-block-background in 8.3.1?

[JI , Xiang]

The thing is that while I could previously use variable-pitch-mode in the rest 
of org buffer and still let source code blocks inherit fixed-pitch face, now 
this seems to be impossible to achieve. With org-block-background face gone, 
even if I already set org-block face to inherit fixed-pitch, the face displayed 
in blocks such as #BEGIN_SRC haskell is still variable-pitch as the rest of the 
buffer. Only plain blocks of #BEGIN_SRC without any language specified are 
displayed in fixed-pitch. Any workaround for this? Thanks.

[JI , Xiang]

Well actually I think the error shows because of another block below the 
emacs-lisp blocks. In this header I just wrote #+BEGIN_SRC without any language 
name. Is it actually wrong and maybe I should have written #+BEGIN_EXAMPLE 
instead? Though I’d still say it probably shouldn’t have failed the export?…
