I have both the system monitors of KDE and GNOME. When I compare the CPU usage of a CPU intensive program, that of KDE reports a 30% usage and 3GB of memory while that of GNOME reports 300% of CPU and same -3Gbs - of memory!
So, my questions:
- Why they reported different CPU usage for the same program while they reported the same memory usage?
- What is the meaning of 300% CPU usage that GNOME system monitor reports?!
System Info: Redhat 6.6 (Santiago) - Kernel: (Linux 2.6.32-504.30.3.el6.x86_64) - GNOME: 2.28.2 - KDE: 4.3.4
When a process is using more than a core you can have value like that. (
100%*3=300%
). It's strange however even for different ways to report it. Did you check it withtop
? ps> Welcome (out) on SuperUser. Is the test made with the same program doing the same things and with the samenice
? Moreover, are the monitors showing the same quantity? – Hastur – 2016-07-25T14:18:05.763I guess you are right, maybe KDE shows CPU usage out of all available cores.

produces same result as GNOME monitor. yes I run the program and have both monitors running at the same time. – Mohamed Moanis – 2016-07-25T14:23:29.683There are many different applets that will work as system monitors. If you refer to some of them, maybe you should add a link to their homepage. BTW check for what they are showing. (Maybe there is the possibility to select overall CPU usage or something else...). PS> with

you can press1
and open the single core usage... – Hastur – 2016-07-25T14:28:02.937
