Moderation helps optimize network throughput and CPU utilization. Interrupt moderation rate sets the rate at which the controller moderates or delays the generation of interrupts. When you enable interrupt moderation, the interrupt rate is lower, and the result is better system performance. At greater link speeds, it creates more interrupts, and CPU utilization also increases.
When a packet arrives, the adapter generates an interrupt that allows the driver to handle the packet. Interrupt moderation allows the adapter to moderate interrupts. This splitting action reduces CPU utilization. Header data split enables the adapter to split the header information from an incoming packet so the CPU does not have to process the whole packet. TX Enabled: The adapter generates a flow control frame when its receive queue reaches a predefined limit. RX Enabled: The adapter pauses transmission when it receives a flow control frame from a link partner. RX and TX Enabled: The adapter generates and responds to flow control frames. Noteįor adapters to benefit from this feature, link partners must support flow control frames. It forces the transmitting link partner to stop transmitting before trying to retransmit. If an overload situation occurs, the device generates a flow control frame. The flow control mechanism overcomes this problem and eliminates the risk of lost frames. Frames are discarded until the overload condition passes.
You can configure flow control under Performance Options properties when Intel® PROSet for Windows Device Manager is installed.Ī link partner can become overloaded if incoming frames arrive faster than the device can process them. Onscreen help is available when Intel® PROSet for Windows Device Manager is installed.Ĭlick or the topic for details: Flow controlįlow control enables adapters to generate or respond to flow control frames, which help regulate network traffic.
Advanced tab layout and feature availability are different when Intel® PROSet for Windows Device Manager* is installed.Some features might not be available, depending on the operating system and the specific adapters installed.For those adapters, see Advanced Settings for Intel® PRO/10GbE Server Adapters. This page does not apply to adapters that have PRO/10GbE in their name. The settings in the Advanced tab customize how the adapter handles QoS packet tagging, Jumbo Frames, Offloading, and other capabilities.
