As far as we know, there is no way to compress reality. The smallest full simulation of a thing is the thing itself.
That means the real world simulation would be as big as the real world. To exchange messages from one side to another means the information has to travel from some point in the physical network to another. Although the nodes may be closer in the physical network than in the virtual world, taking less time, that can't be true for any two nodes.
On average, a full simulation of something will be as physically large as the thing itself, and the distance information has to travel is on average the same virtually and physically.
What if it's not a full simulation? Then you can break those rules. I can draw two galaxies and a spaceship that travels between them in seconds therefore achieving your premise.
Can a restricted simulation ever be computationally faster than a reality/a full simulation? My intuition says no. I can't think of a source.
