Is there reliable stats on performance of Windows server 2008 R2 with intense TCP traffic over IPv6 vs IPv4 ?

I know IPv6 header is larger but easier to process for the routers. but what about Windows? does it have adverse effect on the end-users?

So much depends on your server, nic, apps, and driver, it is difficult to imagine answering this in a helpful way – Mike Pennington Jun 23 '12 at 16:48
OK. is there _any information on IPv6 Windows Server implementation vs RedHat Enterprise latency-wise? With same NICs and best possible driver settings? – Boppity Bop Jun 23 '12 at 16:53
PS when I ask too narrow question I got it closed because its localised. Now I am asking general question still not happy... What to do?? – Boppity Bop Jun 23 '12 at 16:54

The performance is the same, as most of the processing is offloaded to hardware in 2008 R2. Just use enterprise level cards like Intel Pro 10GBps.
