Note: Setting the LAN connection speed to 100 Mbit/s does not reduce performance.
However, the CPU is more efficient if you limit your incoming traffic to 10 Mbit/s.
To increase your CPU performance, set the connected external LAN hub or switch to
10 Mbit/s or to Auto Sense.
Note: If you enable LAN Traffic Smoothing, the connection type defaults to Auto Sense.
Therefore, you do not need to set the connection speed on the external LAN hub or switch.
