Having a smaller website makes it load faster — that’s not surprising.
What is surprising is that a
14kBpage can load much faster than a
15kBpage — maybe 612ms faster — while the difference between a
16kBpage 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:
14kBincludes compression — so it could actually be more like
~50kBof uncompressed data — which is generous. Consider that the Apollo 11 guidance computers only had 72kB of memory.
