Subject: Need help with Ntoskrnl thread causing high CPU
Posted: 23 October 2014 at 10:32am
Found this thread while googling for my problem with high CPU usage by ntoskrnl and it seems like everyone is hijacking this thread, so I'll give it a go myself.
I have constant CPU usage from the System process, between 7% and 10%, Process Explorer traced it back to "ntoskrnl.exe!KeReleaseInStackQueuedSpinLock+0x1e0".
I've generated my own xperf log but don't quite know how to use the Performance Analyser to find the culprit.
Here's my .etl file: http://we.tl/vyn82BeAia
I've tried generating several logs, but it seems they never get bigger than 6mb. Is this normal?
Thanks for any help
