Re: [AUCTeX] running C-c C-c very slow

[Lars Madsen]

Now I'm just wondering.

What is AucTeX looking up at C-c C-c? And why is that lookup needed.

(I hardly ever use C-c C-c, since I'm running latexmk in pvc mode)

But as you've said below in your last message:

Well, that means that AUCTeX does more than thousand file-exists-p
checks on files that are accessed via network.  Not astonishing that
this is slow.  (NFS was just an example.  Samba is quite similar.)

No.

Ok, so how to solve the problem?

  1. You could check if there's some optimization/caching option for
     samba that speeds up file existance checks.

  2. Install a TeX distro locally.
