You should test your setup with a potentiometer too (I suspect it will react much faster). Because what you describe sounds like a classic capacitive drive problem, I strongly suspect your gyro cannot drive the capacitance it's output driver is "seeing". This can be due to a defective gyro and/or the cabling presents a capacitive load that is too high for the gyro to drive. Either way, this is not normal behavior as the angular change should be nearly instantaneous.
