Raising Receive Buffers - Smartek UCC User Manual

7.1.3.3 Raising Receive Buffers

The receive buffer size of the network interface card represents a reserved memory in the system
memory, which is used to buffer incoming data. Especially at the high bandwidth of Gigabit Ethernet
cameras, it is recommended to raise the buffer size for at least the incoming packets (receive buffers) to
the supported maximum. As it is a feature of the network interface card, it usually can be accessed via its
driver settings.
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 81, raise the value of the Receive Buffers property to its maximum value.
