Is Trickplay generation really that excrutiatingly slow? Can it be improved?

[Elekam]

So I recently had to adjust my docker paths causing my library have to regenerate a lot of stuff, for example Trickplay. Sadly the docker paths werent setup to always the same inside the docker, that is my bad.

Now Jellyfin has to regenerate Trickplay for Terabytes of video, and it takes excrutiatingly long. Like 20-30 minutes for 90 minutes of footage. Im not entirely sure but it seems to take 6+ hours for like one percent progress.

Is there any way to speed this up/optimize it or are improvements planned? Or will I just have to schedule this task for in the night and let it take like 1,5 months to complete...

Thanks in advance for any info! :)
