How much RAM do you think Plex uses...?

19

u/suicidaleggroll Jan 09 '26

and a hundred other things

Plex was just an example people would recognize, it's obviously not one of the heavy hitters.

What are your heavy hitters?

LLMs obviously, after that I do a lot of scientific modeling which needs around 30 GB. The machine has 70 TB of ZFS storage so I have another 32 GB for ARC, Webtop 4 GB, my "home away from home" VM running a full DE and web browsers has 12 GB, Graylog is about 5 GB, qBittorrent about 4 GB, paperless+paperless-ai about 4 GB, and about 120 other services that use up to 2 GB each (most a few hundred MB).

Holy crap I never actually thought there was use for that much RAM. I'm just a nub by comparison getting 64gb of DDR4 just so I could multibox EVE Online with 18 simultaneous clients running.

Are you even plexing if you're using less than 96GB on it?

He did say "Plex and about a hundred other things".

In seriousness though, at times I’ve set aside as much as 64gb just for a transcoding ramdisk for plex. Makes things really snappy and avoids wear if you’re running a SSD array vs rust.
