Having a smaller website makes it load faster — that’s not surprising.

What is surprising is that a 14kB page can load much faster than a 15kB page — maybe 612ms faster — while the difference between a 15kB and a 16kB page is trivial.

The reason for this is because of how TCP works, which is nicely explained in the post. But is 14kB even a feasible reality? The author thinks so:

That 14kB includes compression — so it could actually be more like ~50kB of uncompressed data — which is generous. Consider that the Apollo 11 guidance computers only had 72kB of memory.

Once you lose the autoplaying videos, the popups, the cookies, the cookie consent banners, the social network buttons, the tracking scripts, javascript and css frameworks, and all the other junk nobody likes — you’re probably there.
