Fluctuating CPU usage

I just noticed on the dashboard the CPU usage is fluctuating pretty much constantly i.e. stays at one level for a second or 2 then jumps to a different level. This is on the graph.

Normally this is pretty much static and looking at the running processes I cannot see anything unusual. I was wondering if the latest Webmin update may have changed how this works and if not any other idea as to why this might be happening.

Me too!

Yes the information page got some changes and now you can see in real time a consumption of your server resources. If you want to change (even i dont know why) go to: Authentic theme option - “System Information page options” (near the end of the page) - check “Interval for performing update” and change the value to what you want.

Thanks Diabolico for confirming the change.
