Disable The Interrupt Moderation Rate - Smartek UCC User Manual

7.1.3.4 Disable the Interrupt Moderation Rate

To optimize the latency of the data transmission, it is recommended to disable the Interrupt Moderation
Rate feature of the network adapter. This feature changes the way of interrupt generation by an incoming
packet and makes it possible to reduce the delay in the processing of incoming Ethernet packets. It is
usually accessible via the identically named property in the advanced driver settings of the NIC, shown in
Figure 82.
On Microsoft Windows operating systems it can be accessed the following way:
1. Execute "ncpa.cpl", i.e. via the command box of the Windows Startmenu or after pressing
your keyboard
2. Right-click the target network interface card and choose Properties .
3. Press the Configure button below the name of the physical network interface, shown in Figure 79.
4. The settings of the driver can be accessed by choosing the Advanced tab of the opened window. As
shown in Figure 82, set the value of the Interrupt Moderation Rate property to Off or Disabled .
