Maximum Users - dynamite_blonde - 2025-08-26
Hi,
What's the maximum number of users that can be connected to the system at one time? Could I stream to 4000 users on the same network?
TIA,
DB

Jellyfin is meant as a personal media server. While theoretically this is possible, you're likely to encounter MANY bottlenecks along the way, including drive I/O, network throughput, ISP speed, and likely you'd garner some attention streaming to 4k people at the same time.
The overhead for non-transcoded media is minimal, though there is definitely a limit there as well. Jellyfin is not meant as a commercial solution and does not cater to that sort of feature set.

This would be on a local connection, LAN only, 10G backbone.
Is there a commercial version, or similar, to Jellyfin?
RE: Maximum Users - bitmap - 2025-08-26
I am not aware of a commercial-grade open source solution. If everything is on a local connection w/ 10G, your limits are disk I/O if everything resides on the same disk as well as a theoretical network limit of bitrate x streams.

Unless you're sure all 4,000 users will never try accessing the server at once, you can be fine with 10G NICs.
For that amount of users, you will need much higher speeds than just 10G. Unless your videos are really low in bitrate, I would look at upgrading the 10G NIC to something better. And also, I would make sure the drives can support the bandwidth needed for this (so SSD drives would likely be needed to host the media).
