About this tag
Jumbo frames are a network setting that increases the maximum transmission unit (MTU) beyond the standard 1500 bytes, allowing larger packets to be sent in a single frame. On Windows systems, enabling jumbo frames can improve file transfer speeds, especially on gigabit or faster local networks when transferring large files to NAS devices or other PCs. Discussions on WindowsForum.com cover enabling jumbo frames on Windows 10/11 and Windows 7, often in combination with SMB optimization, flow control, and duplex settings. Users troubleshooting slow transfers (e.g., 100Mbps on a gigabit network) frequently check jumbo frame support across all devices and switches. Proper configuration requires matching MTU values on all network endpoints.
