Disable tasks when watching / SSD "inbox" drive.

[Daxi]

Hello,

is or could be there an option to disable / stop intensive tasks while users are watching?

Example:
* 4K UHD rip
* Library has chapter images and trickplay active on library scan (on library scan should not be the issue here).

Such tasks could generate high transfer on the HDDs.
If a user wants to watch a movie now, there could be a bottleneck very fast.

At my server, at maximum there are three users (local network) and the scheduled tasks.

It would be really great if Jellyfin could pause such tasks when a users is watching a video and continues when nobody is watching.


My alternative idea for better performance would be to use a SSD drive for new movies / shows etc.
The files should be then moved when analyzied, added to the DB, chapter images and trickplay images are generates etc.
This would be also a nice solution to avoid the bottleneck of HDDs.


Thanks a lot already for your opinions.
Hope this idea could become a feature in any way.

Kind regards,
Daxi

The max bandwidth for a UHD Bluray is 144Mbit/sec, modern HDD's can transfer between 10-20MB/sec (80-160Mbit) with 4 individual reads from different files (3 for your users , 1 for the library scan). So i think in your case it will be fine if your just playing "rips" which are mostly encoded at a much lower bandwidth.

Whilst I agree that unnecessary maintenance tasks should back off whilst media is being streamed, most of what you're asking for is something to be solved at the filesystem level, not at the service level (i.e., not in Jellyfin). Tiered storage and perhaps a persistent L2ARC and/or 'special' on ZFS might interest you, but make sure you understand what you're getting into as it seldom works how people think it does.
