​Jumbo Frames

When the expected traffic environment consists of large blocks of data being transferred, it might be beneficial to enable the jumbo frame feature. Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU) to a value larger than the default value of 1500. This allows the device to transfer data in larger packets within the network environment. This setting might improve throughput and reduce CPU utilization for large I/O workloads. However, it might impact small packet or latency-sensitive workloads.

Use the ifconfig command to increase the MTU size. For example, enter the following, where <ethX> is the interface number: ifconfig <ethX> mtu 9000 up

Alternatively, you can use the ip command as follows: ip link set mtu 9000 dev <ethX> ip link set up dev <ethX>
