Perhaps I am wrong, but I believed the overhead for a few bytes within a packet was almost zero.
Here's my logic: If the packet is smaller than the 1500 byte maximum packet size then the packet will be enlarged and no additional packets will be sent. 10 bytes / 10 megabit per second = 1 microsecond of overhead to serialize the bytes. A very good network latency is 2 milliseconds. 1 microsecond / 2 milliseconds = 0.05% additional overhead in transmission time The only additional overhead I see in the game program is the time to serialize/deserialize the additional bytes. I can't estimate those since I don't know how your code does this. If this is wrong, or overly simplistic, I'd be happy to learn where it's wrong.
