Explain better in the DOCS advantages of cache (CDN)

with that setup, he is pretty much testing how well cloudflare CDN works
because 99.89% of the requests when to the CF CDN
and that obviously scales to the infinitum
but that’s one of the points I always try to make: Frontity is as fast and as scalable as a static site as soon as you add a CDN
and you should add a CDN
(by the way, all the modern static site hostings like Now, Netlify, Surge… have CDNs)
For the rest of 0.11% of the requests that went into Frontity:
If you use a Node server: much more scalable than WordPress, because it’s Node (which by default is more scalable for its I/O) and it’s stateless so you can easily scale horizontally.
If you use Serverless: then this part is also infinite scalable, like a CDN.
and finally the last thing that needs to be taken into consideration to scale Frontity is how well you cache the REST API

I think creating a "cache" subcategory under "Architecture" can be a good place to document this.
We should document either cache at a Frontend level and cache at a WP level
