 MvdV> For what it is worth, here is mine: (POP nlede01)

 MvdV> root@OpenWrt:~# ping 216.66.84.46

 MvdV> And for my HE tunnel (teminating at AMSIX)

 MvdV> root@OpenWrt:~# ping 216.66.84.46

   The same PoP?

 MvdV> round-trip min/avg/max = 8.154/10.548/11.872 ms

   No mdev? It seems to be several milliseconds...

 MvdV> -+- 82.96.56.14 ping statistics ---
 MvdV> 7 packets transmitted, 7 packets received, 0% packet loss
 MvdV> round-trip min/avg/max = 28.243/29.324/30.897 ms

 MvdV> Almost three time as long as either of mine.

   Yep. But less than half the deviation. With response times as low as this, mdev usually says more than the actual time.

 MvdV> Note: I pinged from my router, not from one of the end system. So that
 MvdV> the latency in my local network was noy included.

   OK. How about the DNS cache influence? You've probably asked for your own PoP's IP more often than mine. What if you try it again?
