Should MTU and MRU be the same?
Typically, the MTU and MRU sizes for a particular network are the same values. For example, Ethernet networks have an MTU/MRU of 1500 bytes, and both of these values are fixed. However, many dial-up networks allow an endpoint system to define different MTU and MRU sizes.
Why is MTU important?
It defines the largest size of the packet that can be transmitted as a single entity in a network connection. The size of the MTU dictates the amount of data that can be transmitted in bytes over a network. The larger MTU results in more data transmission during a single connection, therefore, reduces the overhead.

mru (Dynamic and Static PPPoE) mtu. mtu (Dynamic and Static PPPoE) nas-port-extended-format.
How does MTU affect throughput?
The use of large MTU sizes allows the operating system to send fewer packets of a larger size to reach the same network throughput. The larger packets greatly reduce the processing required in the operating system, assuming the workload allows large messages to be sent.
Should I lower MTU?
A larger MTU (Maximum Transmission Unit) brings greater efficiency in transmitting because each packet carries more data; however, a packet too large may be fragmented and results in lower transmitting speed instead. Optimizing the MTU value on the router’s WAN interface can improve performance and avoid issues.

How to find the correct MTU for a network?
NOTE: Once you get a reply, take 1452 and add 28 to it for you to get the correct MTU size. In the example given above, 1452 is the proper value and the correct MTU size would be 1480 for the network you’re working with. Click the Pearl button and enter “cmd” in the search field then, press [Enter].
What’s the difference between maximum receive unit and MTU?
Lastly, MRU? On the other hand maximum receive unit (MRU) is the largest packet size that an interface can receive, so it’s an ingress interface parameter. In most of the cases MRU equals MTU but it’s not a requirement. You can configure different values for both MTU and MRU to achieve some benefits.
What’s the difference between MTU and Ethernet frames?
Forgive me if you know all this already. MTU is the Maximum Transmission Unit, the largest packet of data that a computer interface will send. For Ethernet the default is 1500 Bytes. Ethernet frames typically are allowed to be up to 1522-1542 (depends on what you count) and the extra space is ‘reserved’ for header information.
