I am not sure if is correct. For me, at least with pnpm run dev, it spawns 2 nodejs nodes, and you show only the usage of the lower one

40 kb seems to be total Memory. Where can we raise this?

I would like to make this feature enabled/disabled based on environment variables.
for infra like netlify cloudflare these metrics will not be available. so this should be by default disabled and only if the user wants and running in a VM or server then should enable from environment vars

I will check it out if we can implement it...
