Tunnels add more overhead (in our case PPPoE adds 8 more bytes). So the next step is, we want to test if our new 9000 byte MTU is actually working and we can reap the benefits of a larger packet size (whether it’s on iSCSI, LAN, whatever) being of course a higher latency but also higher throughput. Optimizing the MTU value on the router's WAN interface can improve performance and avoid issues.
