100% cpu drain few minutes after boot

I have strange problem with CPU drain. For most of the time 4 cpu (of 8 in total) cores run at 100% after few minutes when system boots (by conky).
My desktop laptop is quite powerful but because all of this cpu load it lags even if I play some music and start eclipse (for example).
I run mpstat but I looks rather ok for me - I'm not an expert in hardware topics.


At the time when I write this post I have this processes running:

I already do some solutions posted by Blackwind in topic of kworkers https://bbs.archlinux.org/viewtopic.php … 3#p1055463 but without any results.

If there is any information, logs and other debugs info I could provide ask me about them. Debbuging this problem looks like iceberg to me. There are so many possibilities that I don't known how to even start.

What could be a reason of this cpu drain and how to debug it?

thanks

Re: 100% cpu drain few minutes after boot

Have you run `top`? It will show you which particular process is utilizing the CPU so highly.

Re: 100% cpu drain few minutes after boot

If you are using kde see with graphical utility ksysguard which processes or process is hogging resources.
On gnome check with gnome-system-monitor.

Re: 100% cpu drain few minutes after boot

Thanks for your reply. I installed gnome-system-monitor and everything looks ok. It is my conky that is giving strange informations. I will check conkys configuration file in a free while.
