Mikrotik example:
a) Take true 1Gig uplink to the internet
b) take Mikrotik device with mipsbe processor, configure it to enable 
only V6 and perform a speedtest to the fast.com for example
c) The same device enable v4 only and use HW offloads, fastpath, 
fasttrack and so on and perform the test from b)
d) keep v4 only, disable HW offloads, fastpath fast track and perform 
the test
e) compare results with a)
f) try all above with PPPoE and compare

My results: with v4 and all HW offload supports you can expect about 920 
Mbps. With pure v6 - about 400 Mbps, same or even less with HW offloads 
disabled.

Cisco:
Cisco 6880-X - here we have no problems witch ipv4 and ipv6, but no 40G 
or bigger line cards. Only 10Gig cards is little to less in our IPv6 
world. Cisco 6800 "legacy series" (quotes intended, hope you know what I 
mean) you have to observe combinations with "E" cassis to support 
appropriate supervisor avoiding ipv6 multicast limitations, 1M ipv4 
prefixes limit with supervisors even XL, the 40Gig ports available only 
in 6807 SUP6T chassis of course with "E"
SUP without XL only 128k ipv6 routes, and many others dependencies and 
complexities. I forgot about 6500/7600 series also still wide used - 
problem with shared FIB making it practically poor usable for v6, when 
you make place for v4 prefixes.

Hope this helps.
