I'm sorry, but I didn't have the feeling I had many options left. I've reported 
a serious performance regression and all the answer I've been getting sofar is: 
"well if that is slow don't do that you silly" which is anything but a 
satisfying answer.

Anyways as said I'm just the man in the middle, people are hitting this 
performance regression in real life scenarios. I've done my best to make this 
regression clear and known to you, and now I'm done with this thread, please 
remove me from the CC for further replies.

Regards,

Hans
