I did a few extra things to detect the anomaly and I found that this happens mostly when running on battery (with CPU throttling). The CPU use gets more intense the more power friendly the power scheme is. I created an issue with a linked video because this might be happening only with VirtualBox or some weird combination. https://github.com/pharo-project/pharo/issues/5417 Regards, Esteban A.

I constantly find Pharo eating the CPU of the VM, from 25% on idle to 100%, which of course heats up any laptop.
The Pharo Process monitor doesn't show anything unusual, but I cannot tell from that tool if some process is the culprit.
How can I know what is eating the CPU? Is there a way to kill all the unnecessary process and respawn the needed ones?
I run Pharo 7 within a VirtualBox VM with Lubuntu on a Windows 10 host. But the CPU issue happens only with Pharo.
