Cpu usage while idle

[desty_nova]

Hello everyone!

Recently I updated to a fresh install of the x64 diet version (coming from ruining 32 bits version for almost 1.5 year), but I noticed that cpu usage seems a bit more intense/active than it seemed on the 32 bit system.
Don't get me wrong, I know that CPU will never stop cycling and this is just a sample graph, but I remember very well that the CPU usage would stay in the 0.0 mark for a while before going up.
Can someone please enlighten me where I could start looking or if this behavior is expected?

Well CPU usage is around 0.1 - 0.2 %, which is nearly nothing. Most of the time is spend on Docker and RPI Monitor.
