First of, i know this isn't a Linux support forum, but seeing this forum has some system administrators who use Linux, and i have an account here, i thought why not ask here :wink:

I wonder wondering if someone could explain the screenshot below. How come top displays 94.1% idle while also showing processes which apparently are taking 27% and 23% of the cpu.

According to these details, what would my actual CPU-utilization be?

Any input would be appreciated :)

if you have dualcore cpu max is 200%.

Thanks JIV, it is a dualcore.

But it still doesn't add up then. Cause the above screenshot then shows a combined total of 188% idle , while the individual processes show considerably more CPU-utilization. What explains this difference?

not sure, check with htop.
