This is just one of many settings that you may have to adjust to fully optimize your router. The MTU size is a setting that determines the largest packet size that can be transmitted through your system. These packets are measured in octets, or eight-bit bytes.

As a rule of thumb, a larger MTU size will increase bulk protocol throughput. Fewer packets with the same amount of data are processed when the MTU size is increased. However, the tradeoff is that may lead to delays in subsequent packets, resulting in lags and minimum latency. On the flip side, a smaller MTU size will result in more overhead and acknowledgements that must be sent and received.
