Oh Jan, sorry I am really embarrassed... I am an Akonadi user and just quickly 
tried Trojita for comparison, so I did not notice the oldest messages were at 
top, sorry for that!
As a matter of fact, last time I somehow changed that setting, so I was 
confused now, sorry for that. 

About the performance issue: I am willing to do some testing ... I guess I 
will do a series of testings, to make sure it's not a random problem.

What else are you interested in? 

Stay tuned ...
