How to Find the Best MTU Size？

First of all, we must understand what is the best MTU size

1) When the local MTU size> the network MTU size, the network will unpack. This will increase the number of data packets and also increase the time for unpacking and grouping;

2) When the local MTU size <the network MTU size, although it can be directly transmitted, it does not fully utilize the performance of the network and does not give full play to the maximum transmission capacity;

Therefore, to set the most appropriate local MTU size is to make the local MTU size = the network MTU size.

What Is Jumbo Frame?

Image
In computer networks, jumbo frames refer to Ethernet frames whose payload exceeds the limit of 1500 Bytes by the IEEE 802.3 standard, and are specifically designed for Gigabit Ethernet. Generally, the segment from 1500Byte to 9000Byte is called: jumbo frames, and then from 9000Byte to 64000Byte is called Super jumbo frames. Jumbo frames improve data transmission efficiency by sending a bigger frame of data instead of the standard one. The standard data frame has 1500 MTU size and the jumbo frame is typically set at 9000 MTU value size when enabled. Each manufacturer has different settings. For example, Ankmax UC31G2 USB 3.1 to 2.5GbE adapter has 4088Bytes, 9014Bytes, 16128Bytes and so on.Jumbo frame improves data transmission in two ways.  First each frames sent have “overheads” or information regarding those frame. By sending out a jumbo frame instead of standard, you end up sending out more data with the same amount of overhead. The second way is that by sending a bigger amount o...
