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?
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.
