Should I Disable Receive Side Scaling?

What is auto disable gigabit?

Auto Disable Gigabit: When enabled, any Ethernet connections will be limited to 100Mbps, which requires less power.

You can choose to enable this at all times or, for laptops, just when a battery is being used..

Should I disable Energy Efficient Ethernet?

During periods of low data activity, Energy Efficient Ethernet (802.3az EEE) allows for less power consumption by 50% or more while retaining full compatibility with existing equipment. If your modem (ex: Arris 6190) supports EEE, you could enable or disable EEE to reduce the power consumption of your modem while idle.

How do I disable flow control?

You can disable and re-enable flow control at the Global CONFIG level for all ports. When flow control is enabled globally, you can disable and re-enable it on individual ports. To disable flow control, enter the no flow-control command. To turn the feature back on, enter the flow-control command.

How do I know if TCP offloading is enabled?

Open Device Manager. Under Network Adapters, double-click the network adapter that you want. On the Advanced tab, click Enabled or Disabled in the box next to the TCP offload entry.

What is maximum RSS queue?

8Emulex adapters support up to 8 RSS queues. The Emulex NIC adapter uses two CPU cores (one physical and one logical on hyper-threaded systems) for default network communication. Therefore, total number of available RSS queues to an Emulex NIC is minimum of 8 and (total number of physical cores in the system – 2).

What is TCP Chimney Offload feature?

TCP Chimney Offload is a Microsoft Windows feature. It transfers Transmission Control Protocol (TCP) traffic processing from a CPU to a NIC that supports TCP Chimney Offload. Moving TCP/IP processing from the CPU to the network adapter can free the CPU to perform more application-level functions.

What is vRSS?

In this topic, you learn about Virtual Receive Side Scaling (vRSS) and how to configure a virtual network adapter to load balance incoming network traffic across multiple logical processor cores in a VM. … vRSS is dependent on Virtual Machine Queue (VMQ) in the Hyper-V host and RSS in the VM or on the host vNIC.

How do I enable virtual network adapter?

To enable a network adapter using Control Panel, use these steps:Open Settings.Click on Network & Security.Click on Status.Click on Change adapter options.Right-click the network adapter, and select the Enable option.

What is interrupt moderation rate?

Interrupt moderation is a driver feature that allows the user to manage the rate of interrupts to the CPU during packet transmission and reception. … As a result, determining the optimal interrupt moderation settings usually involves a trade-off between latency and throughput performance.

What is Vmq Hyper V?

The NDIS Virtual Machine Queue (VMQ) interface supports Microsoft Hyper-V network performance improvements in NDIS 6.20 and later in Windows Server 2008 R2 and later versions of Windows Server. … Writing VMQ Drivers provides more detailed information about writing NDIS VMQ drivers.

How do I turn off side scaling?

To disable Virtual Receive-side scaling using Device Manager Expand Network adapters, right-click the network adapter you want to work with, and then click Properties. On the Advanced tab in the network adapter properties, locate the setting for Receive-side scaling and make sure it is disabled.

What is TCP IP offload?

TCP offload engine is a function used in network interface cards (NIC) to offload processing of the entire TCP/IP stack to the network controller. By moving some or all of the processing to dedicated hardware, a TCP offload engine frees the system’s main CPU for other tasks.

What are RSS queues?

Receive-Side Scaling (RSS), also known as multi-queue receive, distributes network receive processing across several hardware-based receive queues, allowing inbound network traffic to be processed by multiple CPUs. … It also shows how many interrupts were processed by each queue, and which CPU serviced the interrupt.

What is RPS in networking?

Receive Packet Steering (RPS) is similar to RSS in that it is used to direct packets to specific CPUs for processing. However, RPS is implemented at the software level, and helps to prevent the hardware queue of a single network interface card from becoming a bottleneck in network traffic.

What does receive side scaling do?

Receive side scaling (RSS) is a network driver technology that enables the efficient distribution of network receive processing across multiple CPUs in multiprocessor systems. … The NIC implements a hash function and the resulting hash value provides the means to select a CPU.

How do I know if RSS is enabled?

To verify this in a Windows guest operating system:Open the Device Manager, navigate to Network adapters, and right-click the adapter you wish to enable RSS on.In the Properties window, click the Advanced tab, then click RSS in the list on the left side.Change the Value to Enabled and click OK to close the window.

What is large send offload v2?

In computer networking, large send offload (LSO) is a technique for increasing egress throughput of high-bandwidth network connections by reducing CPU overhead. It works by passing a multipacket buffer to the network interface card (NIC).

Should I disable flow control?

If you do choose to disable flow control, it makes the most sense to disable it on both endpoints. Mismatched configuration could potentially cause performance issues or other problems. Ideally, depending on vendor recommendation, the flow control setting would be the same across the board.
