I'm not denying bad internet exists.
I'm saying that the impact of dropped packets and poor latency falls much worse on sites that have multiple connections and dozens of files to download than a single bundle.
Also in those circumstances, the 13kB would also take "seconds".
The situation described, where the 13kB file takes milliseconds but the 500kB file takes seconds, is what is unrealistic. It's an invention of an LLM.
Chances are two different 13kB files would be far worse in those circumstances than a single 500kB file.
I don't know why I'm still answering this thread, because it's clear I'm not being understood, and this is all arguing over a flagged AI slop article that no-one wrote.
