@AlexLardschneider Hello again and welcome to the Rockstor community.
Does this high processor use also persist if you do not have a web page open on the Rockstor Web-UI Dashboard (where all the fancy graphs are). That page can take a lot of work to produce for both the client and the Rockstor machine, but usually it’s more on the client side actually: ie lots of java-script running in the browser. Also could you give an indication of the hardware you are seeing this high cpu usage on. Rockstor is not really that light weight as it’s (currently anyway) a full CentOS install. We currently have the minimum system requirement as follows:

But this is probably due to be updated to include a dual core processor and the 2 GB ram is also probably a bare minimum.
I’m not sure we actually have anything to ‘fix’ here actually. We have not previously had a report of this actually. Lets see what hardware you are running on and take it from there. Also if there is no Web-UI open at all, the most likely actual use case, then you should get even less cpu usage as there are processes that run to serve some live info in the Web-UI header also. But the Dashboard is definitely a heavy user of scraping system info to display it ‘live’.
Hope that helps.
