wdf01000.sys causing severe latency

 

I have been dealing with severe latency issues (probably with Wdf01000.sys) on this rather new Dell computer.

Somebody help me or I want to return this computer. I have been dealing with this for months. It is killing my business.

latencymon reports the following:

_________________________________________________________________________________________________________
CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:15:42 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 4431.70
Average measured interrupt to process latency (µs): 5.277287

Highest measured interrupt to DPC latency (µs): 1092.80
Average measured interrupt to DPC latency (µs): 1.73730


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 303.797784
Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Highest reported total ISR routine time (%): 0.002452
Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Total time spent in ISRs (%) 0.002452

ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0


_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

Highest DPC routine execution time (µs): 7383.474238
Driver with highest DPC routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

DPC count (execution time >=4000 µs): 4


_________________________________________________________________________________________________________
REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

Process with highest pagefault count: svchost.exe

Total number of hard pagefaults 6766
Hard pagefault count of hardest hit process: 1734
Number of processes hit: 55

What shows in Reliability History Report?

Google says wdf01000.sys errors might be a bad driver. Have you installed any questionable drivers or tried to install any devices that require drivers?

I found something helping a lot, but it's not enough:

- disabling Intel Management and Security Application Local Management Service

This really helps a lot. What is the counterpart of permanently uninstalling Intel Management Engine Components? Maybe I can even uninstal more of those Intel applications?

Then, I went a bit further:

- disabling the onboard soundcard
- disabling the onboard Lan + Wan card
- disabling the Bluetooth card
- disabling the 3 Intel Proset/wireless services

All this came by chance and trials. Maybe we can find a pattern, find a cause, and go further without having to use a disable computer and continuously turn on and off features?

I have never seen wevtsvc.dll before. It shows in the last few days an enormous amount of "successful application reconfiguration" on programs or apps that I have not used in months.

Does this from msinfo32.exe help?

I know several gamers have remarked that moving the nvidia 3000 series videos card to a different slot which will reduce its capabilities solves the problem I am having. That is not an option for me. I do a large amount of Adobe work which requires this videos card.

Adrian, thank you for offering help. I have disabled many things on this computer. I have disabled the onboard Lan + Wan card and the Killer Ethernet controller, even at the same times. I have not disabled Bluetooth, since I am using it. Five months ago I was not running into this problem. Also, I have uninstalled the nvidia video adapter and tried several versions. I have temporarily disabled Norton.

Now, I don't know about the Intel Proset/wireless services. Am I missing something? What about all these Wan miniports I have listed under Network Adapters?

I use an RME UCX II digital audio interface and have disabled all ADAT and SPDIF inputs and outputs. 

I have a Del KB7221W keyboard and mouse that seem to use USB and Bluetooth. AM I wrong about this?

I am certain I have disabled or removed many other items like Dell Peripheral Manager. I appreciate any help you can offer. 

1428

I also disabled several other audio drivers that were not RME.

1. This website says it's part of Windows.

https://www.bleepingcomputer.com/startups/wevtsvc.dll-25743.html

2. Like wdf01000.sys , it's part of Windows. Looks like Windows is getting slowed-down so much, it can tell it can't operate properly and it's trying to let you know.

3. No, Keep your Nvidia GeForce RTX 3060 Ti in it's proper slot. Clean-Install the latest WHQL driver from nvidia.com. There is no slow-down or Latency problems with Nvidia 3000-series cards or drivers. If you don't game (and are that worried about it) you can alternatively install the latest Studio-Driver.

I have recently helped some Dell customers here on the forum with various Latency issues. It always comes down to one thing ... Either Dell has pre-loaded some flakey software (or heavy drivers suites) or the owner has installed some software and/or drivers (after they got computer) that is using-up too many CPU cycles.

Would you be open to thoroughly erasing the C-Drive and clean-installing Windows? Not Dell's, but Microsoft's from here:

https://www.microsoft.com/software-download/windows11

You install to a blank C-Drive SSD, to it's "un-partitioned space". If you want to try it, I can provide you with some more detailed directions.

I have spent the past day doing all you wrote about. Unfortunately, nothing worked. I installed the latest firmware and then made 2 changes. I disabled both Intel SpeedStep and Intel Speed Shift.

I did not think I was able to do this from many people. I have been using ThrottleStop 9.5 for the past week and thought it was preventing the CPUs from reducing power. After 14 minutes, LatencyMon has not reported an issue. This is a first for me.

Please let me know if I am doing something dangerous to my computer. I did buy this computer to be fast. I have a bad feeling that it will all go south now that it is working,

1. Not sure what that means. You clean-installed Windows ?

2. Yes, if you are having problems with a computer ... you can try flashing your firmware (up to the current version) ... as it might help it to run better.

3. No, I've never had to do that... but some owners have had success with that, especially on laptops.

4. No, I've never had to do that... but some owners have had success with that, especially on laptops. Glad to hear it is working better for you.

5. As I understand what Throttle-Stop does ... it should be fine. As long as it stays cool-enough and you keep it plugged-in to AC-Adapter (to compensate for the additional power-draw).

1. No, I did not clean install Windows.

3. Disabling Intel SpeedStep and Intel Speed Shift made the greatest improvement in latency.

4. Not really sure ThrottleStop worked. Maybe a little.

5. This is a desktop computer.
