Rendering not getting picked from cache

Question

Sitecore 9.3 - JSS

I was working on the performance aspects of my application. And I checked the details on Stats.aspx

The different JsonDatRenderer are for different Websites hosted on the instance.

1. I am unable to identify the cause that why From cache was 0 for all other than the one website.

2. And, also we are not getting data from the cache in the 'JsLayoutRenderer'

The site settings are similar for all the websites.
