[System] cpu is consuming 100

[viniciusbrbio]

HI,

I'm trying to watching streaming and my 4 cpus is consuming 100% in all web browsers (firefox, chromium and falKon). This is umbelivable. For sure, this is not a browser problem, but what could be?

You need to find the specific site(s) that are doing this. It seems to be three tabs.

[viniciusbrbio]

Is the one streaming football.

[viniciusbrbio]

Is the one streaming football. There is just one website.

[claydoh]

But what is the url? Maybe they have a crappy Flash video player that is just terrible.

In these sort of cases I like to use the application called System monitor, also know as ksysguard.
The GUI allows simple ordering of applications, memory and CPU usage.

Adding to what Teunis suggested-- the easiest way to start the System monitor is just to press CTRL+ESC on the keyboard, then click on the CPU column to find out what is using the most CPU.

Also, that is an old kernel version you are running (4.15.0-15). I assume you are using Kubuntu 18.04. On my K18.04 the kernel is currently 4.15.0-34. I would suggest updating might be in order.

If you do update (and you haven't updated for a long time) I wouldn't trust Discover to do the updates as it appears to be unreliable with a large number of updates. Use the following instead--

sudo apt update

sudo apt full-upgrade
