Windows 10: NDIS.sys Latency

I've found a lot of threads online regarding this issue, dating all the way back to 2012, and across multiple versions of Windows. I now have the same problem with ndis.sys generating interrupts that enter exceptionally long handlers, which creates audio and visual stuttering. I have followed all the advice, updated all drivers, BIOS, even experimented with a "clean boot" which did not solve the problem. Something I have found is that enabling or disabling energy efficient ethernet under the advanced tab of my network drivers properties will reliably produce the issue within 5-10 seconds of being set i.e stuttering for 1-3 seconds. Latencymon shows up to 200ms duration for what I assume is the interrupt handlers during this time. Perhaps the source of this problem is a resource is being put to sleep to save energy and has to be woken up again during the interrupt handler? The issue still occurs whether energy efficient mode is enabled or disabled, but it happens less frequently when it is disabled.


I am on Windows build 19041.685, and my network driver is Realtek PCIe GbE Family Controller latest driver from their website. Haven't checked if it happens on Wifi yet but the Wifi is virtually unusable in my house anyway.


Has anyone ever found a fix to this issue, and is Microsoft even aware of this issue? Can the interrupt handler be dealt with by a secondary core so it does not freeze the main process? I am a hardware engineer, not a software engineer so I'm not very knowledgeable in this area, any help you can provide would be greatly appreciated.


Thanks in advance.

Wdf01000.sys Latency - Windows 10

Hi,

Wdf01000.sys is a Microsoft driver file. The wdf01000.sys
process should not be deleted or prevented from loading each time Windows loads.

We would like to know more about your wdf01000.sys and latency concern:

• Were you getting errors with wdf01000.sys? If yes, Can you send us a screenshot?
• Which program or application were you using in audio recording?
• What equipment or devices were connected to your PC when you were recording audio?

In the meantime, check out this article for tips on how to improve
PC performance.

Looking forward to your response.

 

High latency ndis.sys on battery

Hi *Smile

I have a problem with ndis.sys - NDIS (Network Driver Interface Specification), Microsoft Corporation.
When i use PC on battery, ndis.sys - NDIS (Network Driver Interface Specification), Microsoft Corporation is too high




When i use PC plugged in, there aren't high latency. How can i solve this problem?




Thanks everybody!*Wink

 

DPC Latency with Storport.sys and Wdf0 1000.sys

Sorry when I went to post it looked much better than it does there.... So I can see how that wasn't the greatest piece to look at.

Here is the screenshot you requested.








Power Plan Settings: High Performance
Turn off disk after: 20min
Sleep/Hibernate: Never
USB Selective Suspend Setting: Enabled
PCI Express Link State Power Management: Off

Processor Power Management

• Maximum Processor Frequency: 0MHz
• Minimum Processor State: 100%
• System Cooling Policy: Active
• Maximum Processor State: 100%

I believe the Power settings are mostly the generic High Performance. If I changed anything it was the sleep function as I often access this computer when I'm at home.

As for staying with my old computer. I agree, I definitely could have, but it had been 3 years since I last built that system so I figured it was time to step it up. I also use the Creative Cloud often and my system could use a boost in speed. Plus the old components are now in a second tower and being used for offloading things to free up this computer for recording (such as rendering video, etc).

I plan to add 32GB more to the RAM over the next two months and a new 1080ti video card. Someone also told me adding an internal Soundcard might help as well, although I don't see what it has to do with this latency issue.

Thanks again,

Brad
