Large Send Offload (IPv4 and IPv6)

This setting sets the adapter to offload the task of segmenting TCP messages into valid Ethernet frames. The maximum frame size limit for large send offload is set to 64,000 bytes.

Since the adapter hardware is able to complete data segmentation much faster than operating system software, this feature may improve transmission performance. In addition, the adapter uses fewer CPU resources.

To change this setting in Intel® PROSet:

This setting is found on the Advanced tab of the device’s Device Manager property sheet or in the Adapter Settings panel in Intel® PROSet Adapter Configuration Utility (Intel® PROSet ACU).

To change this setting in Windows PowerShell*, use the Set-IntelNetAdapterSetting cmdlet. For example:

Set-IntelNetAdapterSetting -Name "<adapter_name>" -DisplayName "Large Send Offload V2
(IPv4)" -DisplayValue "Enabled"

Possible values for this setting are:

  • Enabled

  • Disabled
