Host speed/VFIO question and media order speed?

[Gotta]

You have more important things to worry about than the NVMe drive's throughput (even a SATA SSD is fine).

You HAVE to encode your media for maximum compatibility.  Transcoding DOES NOT scale to that many users.  And definitely not with a P2200.  H264 main, 8-bit, SDR video.  Stereo AAC audio.  External SRT sub files or burned in subs.  That will ensure max compatibility and minimize transcoding.

If you can achieve 100% direct play, you could run Jellyfin on a potato.

RAM doesn't matter too much once you have more than 16GB of it.  I have 3 instances (2 for testing) and cumulatively uses less than 4GB of RAM most of the time (library scans spawn a lot of ffmpeg processes).

TLDR; Good luck, you're going to need it.

Ahh yeah fair enough, the DirectPlay is the way to go, that's what i've currently been doing honestly, i don't ever see transcoding being done lol
but yeahh i have a AMD 3950x CPU, i can also use too, i wish i had an intel for quicksync lol! almost debating on buying a 14900k for the UD770 IGPU and just quicksync off that, could probably get away with buying a ddr4 board that supports the CPU, so i could use my 128GB RAM, 

but im tied between either doing the CPU swap - or buy a AX1600i to replace my RM850X and grab a Radeon 7800 xt to replace the Quadro P2200 as a host, i use 3080Ti for other VM/Games.

Thanks again btw!
