I have org-mode file with more than 10k lines of notes and traversing through the tree (just basic up/down movements) is very slow (to the point that it's unusable). What can i do to make it work faster?

I know i can split the big files into many smaller ones, but i want to have it encrypted (into *.org.gpg) and don't want to enter the password every time i open different file.

Thank you for help.

    don't want to enter the password every time i open different file <-- you don't need to do this when you use a key chain that you unlock at login time.

  • @rekado: could you elaborate a little more on how to do that?

  • @Dan: there are many implementations of key chains / key rings. On Fedora I use gnome-keyring, which is configured to unlock the keyring (containing my GPG and SSH keys) on login.

linum-mode is also having a big impact on the speed of browsing orgmode files, so it's better not to use it.

  • This is better - when i set it to nil (global-linum-mode in my case) i can have whole tree visible (without content) and there are no lags. Thank you.

Collapse nothing:

Your file "will be fast" again.

I know post already has an accepted answer, but thought this might still be helpful to some people. If the cause of your slowness is global-linum-mode but you don't want to lose the line numbering, replace global-linum-mode by global-display-line-numbers-mode (see https://www.emacswiki.org/emacs/LineNumbers). Requires Emacs 26 or higher.
