​General Tuning

1. ​Use the proper cabling for your device.
2. ​Verify PCIe compatibility with the Intel® Ethernet device(s).

   See ​Check PCI Express (PCIe) Slot Capabilities

3. Adjust BIOS settings for performance workloads. See ​BIOS Settings.
4. ​Disable the Firewall (if possible).
5. ​Adjust the Network Adapter properties for the workload.

   Common options to consider are:

   • ​Speed and Duplex
   • ​Jumbo Packet
   • ​Interrupt Moderation
   • ​Receive and Transmit Buffers
   • ​Offloading features that offload processing tasks from the CPU to the network adapter, such as:
     • ​Checksum offloading
     • ​TCP/IP offloading
     • ​Receive Side Scaling (RSS)
   See Baseline Performance Measurements and Tuning Methodology.

6. ​Use CPU cores local to the adapter for application traffic. See ​CPU Affinity.
7. ​Increase the number of TCP and Socket resources from the default value.
   • For Windows-Based systems, no system parameters have been identified that significantly impact performance, other than TCP Window Size.
