We're veering off-topic, so I'll make this my closing remark.
10 is plenty for "browsing", per se. And having "fast internet" can sometimes cause more harm than good.
I *intentionally* "throttle" my connection when streaming from my "tv provider" (I don't have a "tv", everything is streamed via computer or laptop).
I "throttle" all the way down to 100 KB/s [so literally 1/100th of 10 MB/s] (I get buffer-lag at 75 KB/s but ZERO buffering issues at 100).
This *forces* my "tv provider" to *STOP* sending me 4k resolution video streams! I have no use for 4k because it pegs my very old laptop's CPU at 100%.
Why would I watch an hour or so here and there or an entire Sunday with the CPU pegged at 100% for the entire time? Would KILL this laptop in a matter of days.
100 KB/s seems to be perfect for 720p streaming "on the side" (more than fine for laptop display as "background" to real computer adjacently performing real tasks).
That drops CPU to below 28%.
300 KB/s seems to be perfect if I want to "allow" my tv provider to send 1080p.
At the expense of bumping the CPU up to around 35% and that's enough for the fan kicking up to a higher RPM occasionally.
