The routes look pretty sane to me, although my tunnel is to chicago -
and then it connects to HE.

Just tried again - 184KB/s v6, 745KB/s v4.

Connecting to my own server at MIT from BBN (direct v6 tunnel), I am
getting 3.5 MB/s either way, with v6 a little more variable.  My boxes
are a mix of netbsd-4 and netbsd-5.
