Yes. but the point here is consulintel's connectivity, not IETF's :-)
Sometimes we can see latency using IPv6 is lower, and it can be sometimes 
higher than in IPv4. What it should never be is *hugely* higher...

This line of thinking is what is causing the comments about the global 
ipv6 network's lack of quality...

Staying quiet and hope it will improve with time, doesn't help -- issues 
should be FIXED!
IMHO, this is the difference between a real network and a toy network.

Sure, if the NAT boxes are weighting a lot on your network's performance, 
and you can find a 6to4/teredo relay near you (in terms of latency).

i.e. overlayed end-to-end :-)

You should also take a look about "how slower is it?"

Kicking your transit provider's butt to provide native v6 should also be on your 
priority list, right? (or change provider).

I'm also a strong defender of placing one's wallet ahead of one's mouth!
