Why 1000 Mbps Isn’t Just 125 MB/s: Understanding Network Overhead and MTU

Although a 1000 Mbps link theoretically carries 125 MB of data per second, protocol headers, Ethernet framing, MTU limits, and VLAN tags reduce the effective throughput, and using jumbo frames can raise efficiency from about 97.5 % to 99.6 %.

Why a 1 Gbps Ethernet Link Rarely Hits 125 MB/s and How Jumbo Frames Help

This article explains the difference between decimal and binary data units, how Ethernet frame overhead and protocol headers reduce the theoretical 125 MB/s throughput of a 1 Gbps link, and how increasing the MTU with jumbo frames can improve efficiency.
