Memory, Swap and their relationship

[cifri]

I'm still new to the world of Jellyfin, I found it about a month ago.
I really like it!
Many of my questions have already been answered or answered here.
I don't quite understand one thing, the Jellyfin server uses quite a bit of RAM (8GB, max 22%), but it still starts to fill up the swap (1GB) area when transcoded. If it reaches 100%, everything works fine. Uptime is already 16 days, and the swap fluctuates between 70-100%. How normal is that?
Is it worth buying an ssd with a high TDW under the system?
Or can the work be outsourced to memory?

"(8GB, max 22%)" the OS is also included

The operating system determines when to right to swap or memory. I don't constantly monitor my server's usage, but the testing I've done in the past showed that it rarely used swap, if ever. But I have 32GB of RAM.

The amount of disk writes that a Jellyfin server with a few users produces is not a concern for SSD endurance. Any consumer SSD is fine.

Thanks for the answer, then I'll double the memory to begin with.
