Some network adapters allow you to optimize performance for high audio/video traffic. For many deployments, it is sufficient to use the default settings on your network adapter. If your network adapter supports optimization, it is recommended that you increase the receive and transmit buffer settings on the network adapter to three times their default value in the following situations:
- If you anticipate audio and video traffic on any particular
Audio/Video Conferencing Server or Audio/Video Edge Server to
exceed 200 to 250 Mbps.
- If your servers experience packet loss on the network.
 Note: |

| Increasing receive and transmit buffer settings can improve performance but will also consume system memory. |
You can use the following procedure to change these settings on many network adapters. However, the procedure varies depending on the manufacturer and is not available for all network adapters.
