Hi Eric,

if you want to hunt for more improvements, looking at
this table, much can be gained by turning off the
clocktable in the agenda and only turning it on
interactively with "R" when you really need it.

Hmmm, `org-up-heading-all' still gets called, this should no longer  
happen.
I wonder why, when.

If you want to help:

1. reload uncompiled-code:

    C-u C-c C-x r

2. Arm the function

   M-x debug-on-entry RET org-up-heading-all RET

3. TUrn on debugging on error (needed, but hard to explain here)

   You can best do this from the "Options" menu, "Enter Debugger on  
Error"

4. Produce your agenda.  You will get a backtrace buffer, which I  
would like to see...

Thanks.

- Carsten
