Basically none. The satellite link isn’t getting traffic directly between you and the server you are reaching - the satellite just relays the data to the nearest ground station that then uses the normal fibre network to get the rest of the way.

Even if you managed to reconfigure starlink to be a peering network rather than an access network, you’d still have the issue that the starlink network as a whole has orders of magnitude less bandwidth than even one under sea cable
