Hello everyone,

First of all I want to thank you Qubes OS team for such a great everyday tool that keeps me calm every day :)

I am experiencing strange issue with performance after waking up from sleep:
Sometimes after resume from sleep my laptop slows down a lot and the only thing that helps me is to do a reboot.

I've experienced this with R3.2 and now I have the same on R4 and it's really frustrating.

Also the problem is that I have no idea how to debug and find the actual reason why it's happening.

Does anyone have an idea why this is happening? Or any idea how to find the reason?

Dell Latitude E5470
Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz
total_memory : 32429 mB

Thanks,
Andrey

I understand the issue. It was caused by C-States http://www.dell.com/support/article/nl/nl/nlbsdt1/qna41893/what-is-the-c-state-?lang=en. I turned this off in BIOS and there were no problems after that.
