[O] Performance problem when switching agenda views - need for cache?

[Rainer Stengele]

Dear all,

let me show some times I clocked using my precious org system.

Many a times I look at my weekly agenda view, working on the items of today and 
looking back over the weekdays to
quickly find todos I have to to add further notes and clock times.

Now, sometimes I do not find the right todo in the weekly view, so I activate 
the list of all open todos
in order to find the appropriate one.

This process, switching to "all todos" and back to "weekly agenda" takes about 
18 (!) seconds netto.
This is a lot! It psychologically prevents me to use the org system as I should 
and would like to.
I already tried to fix my weekly agenda view in a separate frame and call the 
"all todo" agenda in another frame,
just to go back to the first frame and continue to work there.
This does not seem to work (agenda is updated everywhere). If it would work it 
would just be something like a cache mode.

How about you orgers out there? Do you have long waiting times and therefore 
usability downsides?

my settings:

GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600) from trunk 2011-02-16 on 
LENNART-69DE564 (patched)
Org-mode version 7.6 (release_7.6.88.gd1c9)


by the way:

it takes me

        0.0

to get to see the org version I use!!! Can't explain why. My PC is a Windows XP 
SP3, P5 3GHZ, 3GB RAM. Runs perfectly.
