Issue is network saturation. Most VPSs have limited bandwidth (1Gbps), even if their CPUs could serve tens of thousands of req/s.

Even 1 Gbps is plenty to handle 1,000 connections unless you're serving up video.

That's 1 Mbps per user. If your web page can't render (ignoring image loading) within a couple seconds even on a connection that slow, you're doing something wrong. Maybe stop using 20 different trackers and shoving several megabytes of JavaScript to the user.

The thread is about self-hosted CDN capabilities. Serving large images and video is what CDNs are for. I’m just talking technical limitations here, chill a little bit with the “your web page”.

You can always host your stuff on a few machines and then create a few DNS A records to load balance it on the DNS level :)

This sometimes works, sometimes not. Because of how DNS resolution works, you're totally at the mercy of how your DNS resolver and/or application behave.
