Play like that one guy a few months ago with all the settings turned to the bare minimum to make the game work and S/Eing, portals and waypoints etc are even faster than d2 LoD.
I doubt that shortens the Pindle portal delay by a lot, cause that delay is there for a reason.
Blizzard didn't take such measures with Drognan, at least they didn't take into account that you could put him at the town area limit, in the end you get an instant inventory reset =]
