Sometimes, you may find that you have issues with network performance or bandwidth utilization, which may be related to the MTU settings. If that affects your efficiency, you can consider changing MTU on your computer. This post in MiniTool will teach you how to change MTU in several ways.
MTU (Maximum Transmission Unit) is a necessary parameter which defines the maximum size of a packet that can be transmitted over a network. Therefore, by changing the MTU, you can enhance your network performance. In this way, you can browse the website more efficiently and smoothly.
Larger MTU are associated with reduced overhead. Smaller MTU values can reduce network latency. In many cases, the MTU depends on the underlying network capabilities and must be adjusted manually or automatically to avoid exceeding those capabilities. The MTU parameter may be associated with a communications interface or standard. Some systems may determine the MTU at connection time, such as using path MTU discovery.
