Gas Overhead

As a product that provides great added value, the code needed to achieve abstraction, redundancy, access control, and retry management features incurs gas overhead in both source and destination chains.

At present, the average gas overhead when sending messages of various types through a single GMP with abstraction is as follows:

GMP	uint256	string
Axelar	159880	167419
Layer Zero	114439	117165
Wormhole	152236	151730
CCIP	146529	149540
Hyperlane	208170	211395

The values are expressed in gas units.
