How fast the teleport happens can be adjusted with the WALK.TELEPORT_TO_VIEW_ACCELERATION setting. It’s in [m / s^2] and the default value is 4. If you lower the value the teleport will be slower.
maxTime sets the upper bound for the teleport time, so it doesn’t affect the speed for close views. It only affects the speed for distant views, if the acceleration given above cannot make the teleport hapen within maxTime.
