It seems the better solution is to not use HTTP server software that employs this slow start concept.
Using my own server software I was able to produce a complex single page app that resembled an operating system graphical user interface and achieve full state restoration as fast as 80ms from localhost page request according to the Chrome performance tab.
The article says this is not a TCP layer technology, but something employed by servers as a bandwidth estimating algorithm.
You are correct in that TCP packets are processed within the kernel of modern operating systems.
Edit for clarity:
This is a web server only algorithm. It is not associated with any other kind of TCP traffic. It seems from the down votes that some people found this challenging.
