Dear Tom Reed, my experience is that it doesn't burn as hot, but yes much much longer. Theory I figured is that surface to volume wise there isn't as much available energy, but I like your point about volatiles.
These observations from my woodstove technology which isn't a straight gasifier as such. Fuel was either a locally available bituminous coal or split radiata pine softwood for the firewood.
