I don’t have a jellyfin server but 1MB/s (8mbps) for each person watching 1080p (3.6Gb per hour of content for each file) seems reasonable. ~3MB/s (24mbps) upload and as much download should work.
Data is transmitted in packets. Each packet has a packet header, and a packet payload. The total data transmitted is the header + payload.
If you’re transmitting smaller packet sizes, it means your header is a larger percentage of the total packet size.
Measuring in megabits is the ISP telling you “look, your connection is good for X amount of data. How you choose to use that data is up to you. If you want more of it going to your packet headers instead of your payload, fine.” A bit is a bit is a bit to your ISP.
@Moneo@SigHunter Networking came to be when there were lots of different implementations of a ‘byte’. The PDP-10 was prevalent at the time the internet was being developed for example, which supported variable byte lengths of up to 36-bits per byte.
Network protocols had to support every device regardless of its byte size, so protocol specifications settled on bits as the lowest common unit size, while referring to 8-bit fields as ‘octets’ before 8-bit became the de facto standard byte length.

1mbps is awfully low for 1080. Or did you mean megabyte rather than megabit?
I had a hunch that writing the actual Upload/download speed tather than mbps was probably wrong. My bad, my internet provider lingo is rusted.
Gotcha. Typically lowercase b=bit and uppercase B=Byte, but it’s hard to tell what people mean sometimes, especially in casual posts.
Come to think of it, I messed up the capitalization too. Should be a capital M for mega.
Why don’t people use Mb/s and MB/s which makes it so much clearer what you’re talking about
Back in the day, the rule was mbit (megabit) for data in transfer (network speed) and MB (megabyte) for data at rest, like on HDDs
So mbit/s instead of Mbit/s ? But the M in Mega is always capitalized though, except the k in kilo.
but why?
Bigger number sounds better for the ISP.
The real answer?
Data is transmitted in packets. Each packet has a packet header, and a packet payload. The total data transmitted is the header + payload.
If you’re transmitting smaller packet sizes, it means your header is a larger percentage of the total packet size.

The best format imo is MB/s and Mbit/s
It avoids all confusion.
