Personally going 10G on my networking stuff has significantly improved my experience with self-hosting, especially when it comes to file transfers. 1G can just be extremely slow when you’re dealing with large amounts of data so I also don’t really understand why people recommend against 10G here of all places.
I somewhat disagree that you have to be a data hoarder for 10G to be worth it. For example I’ve got a headless steam client on my server that has my larger games installed (all in all ~2TB so not in data hoarder territories) which allows me to install and update those games at ~8 Gbit/s. Which in turn allows me to run a leaner Desktop PC since I can just uninstall the larger games as soon as I don’t play them daily anymore and saves me time when Steam inevitably fails to auto update a game on my Desktop before I want to play it.
Arguably a niche use case but it exists along side other such niche use cases. So if someone comes into this community and asks about how best to implement 10G networking I will assume they (at least think) have such a use case on their hands and want to improve that situation a bit.
