The test tube heated from below will heat up faster.
We know that hot water rises up, so when the test tube is heated from below the water gets hot, rises up and the cold water from the top takes its place.
We know that if there is a great temperature difference, heat conduction is faster. Hence in this case transformation of heat is faster as the hot water keeps on going up after being heated and the cold water from the top comes down to take its place.
