Should I disable interrupt moderation rate?

Directly disabling interrupt moderation will give you the lowest possible latency. Of course, this will be bundled with a lower machine performance. For all the gamers out there, if you’re playing a multiplayer game and happen to have a powerful CPU, you should definitely disable interrupt moderation.

What should interrupt moderation rate be?

To improve system performance, you can configure the interrupt moderation rate. This setting defines the number of interrupts per second. Note that decreasing this value decreases the CPU usage. For applications where low latency is critical, this setting should be approximately 8000 interrupts per second.

What does interrupt moderation mean?

With interrupt moderation, the NIC hardware will not generate an interrupt immediately after it receives a packet. Instead, the hardware waits for more packets to arrive, or for a time-out to expire, before generating an interrupt.

Where can I find interrupt moderation?

How to reduce latency in Windows by disabling the Interrupt coalescing

• Go to Adapter Settings.
• Right click the adapter and select Properties.
• In the Networking tab, click Configure.
• In the Advanced tab, select Interrupt Moderation and choose Disabled.

Should I turn off energy efficient Ethernet?

Be sure to disable Energy Efficient Ethernet (EEE). EEE is also referred to as Green Ethernet and IEEE 802.3az. EEE reduces device power consumption when network traffic is low.

Should I disable auto disable gigabit?

When users change the setting to Re-Link and user unplugs and plugs network cable again, the driver will automatically disable gigabit capability. Gigabit has much higher power consumption than 10/100 MBps. For notebook users, it is recommended to turn on this to reduce power consumption.

What is Max IRQ per second?

Max IRQ per Second – from 1000 to 30000 (lets the network card interrupt more frequently) Receive Buffers – from 50 to 500 (allows a smoother flow of packets through the system without dropping or restricting the TCP window size) Transmit Buffers – from 50 to 200 (allows a smoother flow of packets)

Should I disable Energy Efficient Ethernet?

Should I disable priority and VLAN?

Priority & VLAN is automatically enabled when you set up a VLAN on the VLAN tab. You cannot disable tagging because tagging is required for VLANs. Intel® PROSet for Windows Device Manager and Advanced Networking Services (ANS) must be installed to configure VLANs on Intel® network adapters.

Should I disable flow control?

Should you completely disable flow control on all computers and switches? Not necessarily. It is generally safe to leave flow control enabled on computers. Switches, though, should either have flow control disabled or configured such that they will honor received pause frames but will never send out new pause frames.

How do you disable Energy Efficient Ethernet?

Disable power saving on ethernet

1. Open Control Panel.
2. select network and Internet.
3. Pick Network Connections. the screen should look like below.
4. click the network card.
5. right click and show properties.
6. click configure.
7. click power management and uncheck the highlighted item per the image below.

Should I disable Large Send Offload?

Large Send Offload is a technique of improving network performance while at the same time reducing CPU overhead. Apparently it does not work very well, so it was suggested to disable it.

What is the value of interruptthrottlerate in Linux?

Setting InterruptThrottleRate to a value greater or equal to 100 will program the adapter to send out a maximum of that many interrupts per second, even if more packets have come in. This reduces interrupt load on the system and can lower CPU utilization under heavy load, but will increase latency as packets are not processed as quickly.

What do you need to know about ethtool?

Description. ethtool is used to query and control network device driver and hardware settings, particularly for wired Ethernet devices. devname is the name of the network device on which ethtool should operate.

How does interrupt throttle rate affect CPU utilization?

Interrupt Throttle Rate controls the number of interrupts each interrupt vector can generate per second. Increasing ITR lowers latency at the cost of increased CPU utilization, though it may help throughput in some circumstances.

How is interruptthrottlerate set on an Ethernet adapter?

It does this by writing a value to the adapter that is based on the maximum amount of interrupts that the adapter will generate per second. Setting InterruptThrottleRate to a value greater or equal to 100 will program the adapter to send out a maximum of that many interrupts per second, even if more packets have come in.
