[emacs-wiki-discuss] source of incredible slowness found

[Joakim Verona]

I had set emacs-wiki-refresh-file-alist-p to true.
In my case the consequence was that moving tasks to a new day page
took several minutes, when font lock was on.

Maybe this variable can be better documented

this is how it read now:
---
Function that returns non-nil if the file list needs to be refreshed.
If nil, never refresh. If t, always refresh. See
`emacs-wiki-refresh-file-alist-maybe'.
---

this is a suggestion for a new text:
---
If this is a function,  the return value decides if the  file list
cache needs to be refreshed.

If a variable, the value nil meand never refresh. If t, always
refresh. 

Normally emacs-wiki will try to keep the file name cache up to date,
but if wiki files are created outside of emacs-wiki you may need to
experiment with this variable. 

The value t will slow down updating of pages considerably.

See `emacs-wiki-refresh-file-alist-maybe'.
