Seems to be related to the Docker Plugin (focus on the flame profiling):

@RazCrimson do you think that it is related to the temporary patch to get Podman lib work ?

Yea, it's probably that as the hacky generator is a bit greedy for the CPU.

Let me try to make a small fix on this.

Could you give https://github.com/nicolargo/glances/tree/issue2390 a try?

It's again a bit of a hacky solution, but it should ease the CPU usage.

It looks better ! CPU consumption more or less the same than Glances 3.3.1 :)
