What is the actual max packet size for a TCP connection?
Read OriginalThis technical article clarifies the real-world maximum packet size for a TCP connection. While the theoretical limit is 64KB (or 1GB with window scaling), the Ethernet MTU of 1500 bytes is the practical constraint. Factoring in TCP and IP headers (40-84 bytes), the effective maximum data size is 1460 bytes to avoid fragmentation overhead.
