Windows 10: What can cause download latency spikes?

Just built a new computer - constantly spiking to higher download latency making it impossible to play multiplayer games.My previous computer does not have this issue at all.I already reset the network drivers and turned it onto a metered connection, but there is no change.The computer runs on Windows 10 PRO with Ryzen 5 7600 AMD CPU.Any help would be great. Thank you.

Huge latency spikes (freezes, hiccups) while downloading and streaming

Hi guys!

I really need your help on this one. Usually I’m good at troubleshooting and finding solutions without having to start my own threads. This time however, it seems impossible to find a solution. Anyway, here’s the thing:
When downloading through utorrent, steam etc and listening to music/watching videos I get huge DPC latency spikes when touching the trackpad. The spikes result in robotic sound, computer hiccups and freezes (minor 1 sec freezes, every 3-5 seconds) But here’s the weird thing. I don’t get the spikes if I’m not touching the trackpad or IF I have a usb mouse connected to my laptop. For some reason, having a usb mouse connected solves the latency problem instantly. Then I can download, listen to audio and watch videos without any problems even though moving the mouse like crazy. So strange.

I have a Lenovo 710 14’ laptop with windows 10. Bought it a week ago. Kaby lake.

I7-7500u
Nvidia 940mx
8 gb ram
256 gb ssd

I have tried a bunch of potential solutions. Creating a bigger pagefile, updating all drivers to newest and also degrading to Lenovo’s website drivers (older). I’ve disabled bits and windows update. I’ve change the power scheme, so that the processor minimum is 100%. And a lot of other things. I can’t even think about everything I’ve tried.

I’ve used latency mon to investigate the latency spikes. Latency mon says that the culprit is WDF01000.sys. I’ve read that it’s difficult to say which driver uses that file etc. While using latency checker I tried disabling the realtek audio adapter. That made the spikes go away. I’m playing music through spotify, which can be quite bandwidth heavy.
It’s like my computer is really sensitive to heavy internet activity, combined with audio/video streaming.

The task manager doesn’t show anything special when the spikes occur. The system interrupt process take up a bit more cpu and memory, but that’s basically it. Otherwise, the computer works fine. It’s just in the specific situation where I download, stream something and don’t have a mouse connected that this happens.

Any ideas would me MUCH appreciated!

 

Windows 10 v1903 - ntoskrnl.exe & ISR/DPC latency spikes

Unfortunately I do not have a solution, but can report that I have the exact same problem with DPC latency spikes caused by ntoskrnl.exe after upgrading to 1903. All drivers and BIOS are up to date (even reinstalled to see if this would help, but did not).
Will be rolling back.

For stuttering and relatively short freezes it's very possible but it depends on many things like the severity of the latency spike, your PC specs, and how demanding the load is (e.g. 4k is significantly more resource intensive than 720p).
