Internet related would be, back in the early 2000s when I was building out infrastructure of pinkbike/trailforks I was optimizing things and discovered that this initcwnd parameter was hardcoded to something like 2 or 3 packets in the linux kernels. This was causing the initial page to require multiple RTTs to load so I figured I would change that and recompile the kernel to make sure all out pages would be transmitted in one go. This made out site perform a lot better compared to most sites at the time. Funny at the time I was a bit worried that the IETF would discover this and shut us down or something. These days that parameter is default to something like 10 and you can increase it with a config parameter.
