If  you were getting that much of a slowdown, something else was going on.
Granted the MTU is slightly and I mean slightly less than native IPv6 or
IPv4, but it's only by 20 bytes/1500 byte packet. Doing the math, this does
NOT equal a 50% lag. Maybe the issue is that your ISP's path to your IPv6
tunnel provider is not an optimum path? Mine is just a couple hops away
so it's not an issue for me.

This is true.
