Why zram0 is only 8G, while I have 32 Go?
That's normal. Zram is a compressed pseudo-device that you don't want
taking up too much RAM. This is my system (also 32GB):
zram doesn't pre-allocate, it takes up RAM as necessary up to its limit.
$ swapon
NAME TYPE SIZE USED PRIO
/dev/zram0 partition 8G 2.2G 100
/dev/nvme1n1p1 partition 62.5G 0B -1
poc
I would much rather have zram taking up RAM than swap going to disk,
even an SSD.
This is my top summary:
MiB Mem : 63651.2 total, 3935.7 free, 46148.5 used, 9321.1
buff/cache
MiB Swap: 47738.0 total, 34398.2 free, 13339.8 used. 17502.7 avail Mem
