Hi,

I'm using Org-mode 6.0.6b, on a fairly beefy box.  Building the Agenda
view is very slow, 10+ seconds for 16 files with a total of 1119
lines.  All org-files are byte-compiled.

I tried setting org-agenda-files to a single, small file just to test,
and it still took over a second to produce the agenda view.

This doesn't seem right.  Does anyone have a clue what to check?

Something is definitely wrong here.  I have 18 files totaling 14456
lines currently and the agenda displays in 1 second on a not-so-beefy
laptop (1.5GHz Intel P4M) running Linux.

I'm assuming your agenda view is the daily or weekly view.

Try starting with a minimal emacs setup.  Maybe you have some hook
active that is slowing things down.

What kind/how complex is the agenda view you are trying to use?
Multiple tag queries with tag inheritance turned on can take noticeable
time, and property queries can take even longer.

I'm using `org-agenda-list', and the files are quite simple, no
properties, small amount of tags.

To make certain it's none of my other customizations interfering, i just
tried with a clean .emacs, except for the loading org-mode part.

Then I'm afraid that my advice/suggestions must be at an end; I have
only ever encountered slowness when dealing with complex agenda queries.
I'll leave it for others with more and more varied experience to try to
determine what's happening.

The org-files were on an NFS mount on the machine I tried to use it.
*blush*  I'm down to nearly-instant when I fixed that.

Hi,

thank you for bringing up the issue.
I have also been troubled by performance issues with my agenda views.

I have about 12000 lines of org text. Starting this agenda view

  ("A" agenda "prio A agenda"
          ((org-agenda-skip-function
            (lambda nil
              (org-agenda-skip-entry-if (quote notregexp) "\\=.*\\[#A\\]")))
           (org-agenda-ndays 3)
           (org-deadline-warning-days -1)
           (org-agenda-overriding-header "Today's Priority #A tasks: ")))

takes several seconds on my EmacsW32 3 GHz CPU. After changing the tag 
inheritance setting to nil the view shows in about 1 second! Which is 
good enough!

I have the same behaviour here; I had thought that the slowness was
mainly due to some of my agenda files being on a slow flash drive, but
tag inheritance turns out to be a much bigger factor.  Which is kind of
unfortunate, as some of my searches depended on tag inheritance, but I'm
willing to re-tag some things to get my agenda showing faster.

One thing that might help is the following:

A tags/property search will suffer only a little from tag inheritance,  
because it systematically walks through all headlines with all tags  
anyway.

Another view like the daily/weekly agenda view or the TODO list will  
suffer from tag inheritance, because each matching entry will scan  
upward the hierarchy to find out what the inherited tags are, just so  
that the agenda view can display the tags *on demand*.

So you could turn on tag inheritance for tags matches and turn it off  
for other views, using the command-specific option settings, like so:

("A" agenda "prio A agenda"
         ((org-agenda-skip-function
           (lambda nil
             (org-agenda-skip-entry-if (quote notregexp) "\\=.*\\[#A\ 
\]")))
          (org-agenda-ndays 3)
          (org-deadline-warning-days -1)
          (org-use-tag-inheritance nil)
          (org-agenda-overriding-header "Today's Priority #A tasks: ")))

The disadvantage will be that the "T" key in the agenda will no longer  
show any inherited tags, and also that the new filtering-by-tag (the  
"/" key in the aganda) will ignore inherited tags.

Yes, that's helpful (in principle).  I'm going to try it out and see if
it helps much with the actual views I use.  Thanks.
