Hmm. In fact Benjamin took the 2.6.23.16 kernel where there were no 
network namespace code at all. So these differences between 2.6.23.16 
and 2.6.25-rc1 does not show a performance degradation especially 
related to the network namespaces. The important point is the 2.6.25-rc1 
without ipv6 netns and 2.6.25-rc1 with ipv6 netns code applied, I mean 
the second and the third line and we can point that the ipv6 netns code 
does not degrade performances for either throughput and service demand.

right :)

Thanks Rick.
