Some VPNs allow you to customize the MTU of your connection.

However, a large MTU can cause congestion if your network is slow - a large packet occupies the connection for a longer time and causes delays to other data packets. Ideally, the MTU should be large enough to send packets of data efficiently without causing any network delays.Ī larger MTU provides a smoother connection as it sends bigger data packets and requires less processing for a big amount of data. The MTU is the Maximum Transmission Unit, or the size of the largest packet that can be sent in a single layer transaction.
