Larger lines going to the cylinders, smaller diameter steering cylinders, or turning up the pressure on the pump would be the only ways I know to speed the steering up. That or run the pump faster. More voltage, though I don't know how much more you could run before you compromise the reliability or longevity of the pump. You could consider upgrading the pump motor to the brushless motor that Leimbach offers. I know that motor spins faster then the brushed motor.
