I would expect 'impaired' performance for PPTP over WAN links, because
of the way MPPE recovers from lost packets. One lost packet affects all
packets sent until the CCP reset message makes the trip back. If MPPE is
replaced with something better PPTP speeds could be quite adequate, even
on heavily loaded WANs. That is, assuming the tunneled protocol can
handle packet loss. TCP can, I don't know about IPX/SPX or NetBEUI or
SNA.
