Ok, thanks for the explanation.

My current emacs session is running now since 5 hours. The length of the
chain is 131. And this is my buffer list:

.%* *Article inbox*        1592 Article          
 %* *Summary inbox*          85 Summary          
 %  *Group*                  41 Group            
 %* *Completions*           180 Completion List  
    *scratch*               141 Lisp Interaction 
 %* *Messages*           446718 Messages         
  * todo.org             147282 Org              ~/todo/todo.org

I guess, that the slow-down is related to the chain-length. What do you think?
