Low Latency Interrupts
LLI enables the network device to bypass the configured interrupt moderation scheme based on the type of
data being received. It configures which arriving TCP packets trigger an immediate interrupt, enabling the
system to handle the packet more quickly. Reduced data latency enables some applications to gain faster
access to network data.
NOTE: When LLI is enabled, system CPU utilization may increase.
LLI can be used for data packets containing a TCP PSH flag in the header or for specified TCP ports.
l
Packets with TCP PSH Flag - Any incoming packet with the TCP PSH flag will trigger an immediate
interrupt. The PSH flag is set by the sending device.
l
TCP Ports - Every packet received on the specified ports will trigger an immediate interrupt. Up to
eight ports may be specified.

Network Virtualization using Generic Routing Encapsulation (NVGRE)
Network Virtualization using Generic Routing Encapsulation (NVGRE) increases the efficient routing of
network traffic within a virtualized or cloud environment. Some Intel® Ethernet Network devices perform
Network Virtualization using Generic Routing Encapsulation (NVGRE) processing, offloading it from the
operating system. This reduces CPU utilization.
Performance Options
Performance Profile
Performance Profiles are supported on Intel® 10GbE adapters and allow you to quickly optimize the
performance of your Intel® Ethernet Adapter. Selecting a performance profile will automatically adjust some
Advanced Settings to their optimum setting for the selected application. For example, a standard server has
optimal performance with only two RSS (Receive-Side Scaling) queues, but a web server requires more RSS
queues for better scalability.
You must install Intel® PROSet for Windows Device Manager to use Performance profiles. Profiles are
selected on the Advanced tab of the adapter's property sheet.
Profiles
l
Standard Server – This profile is optimized for typical servers.
l
Web Server – This profile is optimized for IIS and HTTP-based web servers.
l
Virtualization Server – This profile is optimized for Microsoft’s Hyper-V virtualization
environment.
l
Storage Server – This profile is optimized for Fibre Channel over Ethernet or for
iSCSI over DCB performance. Selecting this profile will disable SR-IOV and VMQ.
l
S Virtualization – This profile is optimized for a combination of storage and
virtualization requirements.
