Serious question, what does RAM help with in the context of self hosting? I recently bought 32G for my server, and it’s DDR3 ecc so it’s so cheap I could have afforded 64 but I just kept wondering what will I use it for? I rarely go north of 6G usage and that’s with half a dozen services, a Minecraft server etc… I just don’t know what kind of services are RAM hungry.
What are you hosting on Minecraft that isn’t using >=4 gigs?
Just a vanilla server i play on with my son, it’s got 2G and i haven’t noticed anything out of the ordinary. Chunk gen is slow-ish but i suppose that’s CPU-bound.
BTW i exagerated in my initial comment, i looked at the machine and it’s sitting just under 8G of used RAM.
ZFS will use memory to cache. Right now my unraid server is using 16gigs, most of that is being used by ZFS to cache files. 4gigs is all ~20 containers are using.

Also ZFS.
oh yeah i see how that can be hungry

Jesus christ 😅 no idea if you’re jesting

My use case might not be very relatable, but I run a bunch of stuff cached in ramdisk.
One example is if my jellyfin server has to transcode something, I have it use ramdisk instead of my SSD for the transcoding cache.
