org-ql makes org-brain-goto slow

[ionling]

With the newest version of org-brain, the org-ql war introduced. Each time I ran org-brain-goto command, org-ql open all my brain files (140 file entries, toal 414 entires), which make Emacs slow...

Anything help or optimization?

Hi! Yes, it is a bit slow on my computer too. The slow part is having to open all of the files. If you have stuff in org-mode-hook and find-file-hook it takes some time to open the files. It should be MUCH faster when you've run the command once, and all of the files are open. Is it still slow the second time you run it?

There's a bit of discussion at alphapapa/org-ql#88 if you're interested.

Thanks for your response.

I test it again. It spend about 1 second to open org-brain-goto (second time), 0.5 second with the old version in my computer. It's slower.

Wow, I read the discussion in the org-ql issue you linked. This is a difficult problem. I really appreciate the work you're putting in upstream to help improve performance for org-brain.

I've removed the org-ql dependency in the latest commit. Instead a simple cache has been implemented, so org-brain should be faster than before.

Oh, cool. I'll give it a try and report back my experience.
