Have you tried to disable PPTP windowing in mpd config? ENOBUFS is the
errno used by ng_pptp node's windowing code when outgoing window is
full. It is not related to any system tunables. Maximum window size in
current ng_pptp is 16 packets. It can be small for LFNs and can reduce
speed.
I guess I should tune some kernel tunable, but what specific one?
I can recomend you to set
net.graph.maxdgram=524288
net.graph.recvspace=524288
to make 'ngctl list' command work, but it is not critical.
