Why do some websites showing 0 bytes in Chrome’s developer tools

I am doing a page speed optimization for my website and studying how other websites do it. I noticed that some websites such as as Facebook or Ringgitplus show 0 bytes for some of their resources in Chrome’s developer tools, Network tab, while the real content size is several kilobytes.

How chromium Site Isolation and process allocation works for Iframe?

I was with working with a website it contains 6-10 Iframes, Each Iframe contains a web app so obviously there are high chances of that my website get slowed down. So to fix this I tried to understand chromes processes allocation model, I spent hours of time on understanding their model. And what i think is that they create new process for every same same cross orgin iframes and they use the parent process if it is same site same orgin iframe. But here I’m confused with what exactly is a orgin (is subdomain(+1,+2) considered), ?
