CPU spikes every 10s (Docker healthcheck)

Apps and Virtualization
1

Hi,

I am currently running 25.04.

I started noticing CPU spikes every 10s. Not huge, but large enough to be noticeable (~40%CPU while idling, on a Ryzen 4300GE, not a beast, but not super-lightweight either)

I started investigating, and the more Apps are started, the higher the spikes (here I had only 6 apps).

The default healthcheck interval defined by Docker is 30s, but Truenas seems to set it to 10s (a bit aggressive IMHO) (healthcheck.py).

Is there any way to configure it, through the CLI for example? The way I understand it, it looks customisable on an app-by-app basis, in the template, but only ddns-updater seems to use that feature.
