[IPv6] Slower ipv6 speeds normal?

Click for full size
Are these results typical using Comcast's 6to4 Tunnel?

I would not put any faith in that speed, it said my ipv6 was faster then my ipv4, witch is not possible since I'm using a tunnel.

is there a "comcast recommended" way of testing IPv6 speed?

Generally speaking, a tunnel will always be slower than direct end-to-end communication. This is why we're going native dual stack. That should provide an equivalent experience to IPv4.

I thought the conversion to ipv6 doesn't effect speed.

It doesn't. However, if you don't have iPv6 and have to use a tunnel to a free tunnel provider to get it, it might be slow. This is often the case when tunnel servers are overloaded.

Going back to the OP it could be a number of things from MTU to peering. I'm sure NetDog will get you fixed though.
