I liked the server I set up the other day. 512 gigs of ram, 1 gig swap.
We’re using maybe 100gigs currently.
That’d be over 1TB with zram on
This comment is how I learned about zram. Just one question, when is it used?
Fedora enables it on all systems with <4GB (maybe a bit less I forget). It’s trivial to enable/disable it and see if its helpful for your usage.
Yep. I just looked it up.
I assumed it was like windows page file but it’s ramdisk.
Depends on config, ArchWiki recommends optmizing some sysctl values to take advantage of it
it generally starts kicking in after >60% RAM usage even with this config
Me watching my kernel shove 16gb worth of in use virtual memory into zswap in a desperate attempt to run 20 heavy applications on 8gb of physical memory
use a swap file
