Thanks a lot, much appreciated. On that topic I've uploaded the updated 
presentation of my talk with the corrected Unbound results and the 
correction of some other copy and paste errors.

While I agree it would be good to have better performing UDP network 
stacks in Linux, the current ones work for DNS way better than the
TCP stack. This might be optimised for gigabits of web traffic, but 
the not for the quick query/responses DNS has. Even with the current
Linux UDP stack it is possible to run a DNS server that answers more 
than a million requests in a second. You just can't do that with TCP.

So as said we agree that the Community should put more effort in 
getting the Linux people to do better UDP stack instead of switching 
DNS to TCP, which other people have been suggesting.

So long
