Windows 10: Messed Up Cpu Interrupt Cycle Times

Im trying to setup up interrupt affinity policy. I have a i59400f proccessor which has 6 cores so i have been told to set my gpu and usb to 2 and 4 in interrupt affinity policy. My average interrupt to proccess latency is good but my Cpu interrupt cycle times are all messed up.

System and compressed memory eating CPU cycles

Hi Imakuni,

Thank you for posting in Microsoft Community and being part of Windows 10.

I understand your concern about CPU usage by System and compressed memory process. We will help you with this issue.

We appreciate your effort and time spent in resolving the issue.

I would like to inform that Ntoskrnl.exe
is a critical process in the boot-up cycle of your computer.

This issue might have occurred due to malware infection/ outdated drivers/
Runtime Broker. Try the below troubleshooting steps and check if it helps.

Step 1: I suggest you to run a virus scan on your device and check if it helps.

Refer: Security & privacy
(Run Windows Defender scan)

Note: Data or files which are infected by malware might be beyond cleaning and have to be deleted entirely to maintain the integrity of your system, which means there might be a potential for data loss.

Step 2: Turn off the "Show me tips about Windows"

Please do the below steps to do the same.

• Press Start button, click on Settings.
• In the Settings, select the System>Notifications and actions> turn off the "Show me tips about Windows".
• Restart the computer.

• Click on Check for updates.
• Under Windows Updates, click on Check for updates.
• Try to install the updates being shown.

Hope it helps. Try the above and update us the status of this issue for further assistance.

 

Excessive System Interrupts CPU Time

Hello,

I've been having a slight problem with high system interrupt CPU usage for a while now. I have a basic idea of what they are and what they are there for (and, by extension, it's not just some background program I can kill). I recall reading somewhere that
a "healthy" CPU consumption by system interrupts should be somewhere around 0-2%, with maybe occasional spikes around 5%. However, I found (with handy-dandy Task Manager and Resource Monitor) that my system interrupts can end up clocking in anywhere around
20-40% CPU usage (relatively steady, not just spikes), particularly while playing games.

I used LatencyMon to try and determine which files/drivers might be causing issues, and I've seen 4 come up:

• dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation
• nvlddnkn.sys - NVIDIA Windows Kernel Mode Driver, Version 442.59 , NVIDIA Corporation
• HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation
• USBPORT.sys - USB 1.2 _2.0 Port Driver, Microsoft Corporation

I've tried checking all of my drivers, but as far as I can tell all of my drivers are up to date. I reinstalled my graphics driver twice (once via GeForce Experience and once manually). I also tried unplugged all of my USB devices (including my WiFi adapter,
mouse, and keyboard). No luck with any of these though.

I tried searching for a new chipset driver, but I've been having issues finding one for my system (Dell OptiPlex 755 mini-tower).

Any help addressing and potentially fixing this issue would be greatly appreciated.

Thank you,

System Interrupt High CPU Usage

Hi all,

I am using a Windows 10 Home on an Acer Aspire F5-573G laptop.

A proccess which is called 'System Interrupt' is using about 8-12% of CPU all the time.

I've installed all the Windows updates and all the drivers as well but the problem is still not gone.

Would you have any suggestions of what should I do in this case?

Thank you.
