Perhaps the following analogy helps understanding the problem with your
question:

When asking if a humvee is much slower than an Alfa Romeo it is a very
good idea to provide a description of the terrain one refers to: On a
motodrome an Alfa Romeo of course is much faster than a humvee. During a
traffic jam both cars are equally fast. When leaving roads the humvee
has good chances of being much faster than an Alfa Romeo (that may not
even move one meter). HTH.
