This basically puts the amount of memory used at about 9.5GiB (used + DATA - TOTAL), that's on a system with only ~3.7GiB RAM available!

Code:

$ free -h; zramctl
total        used        free      shared  buff/cache   available
Mem:          3.7Gi       3.5Gi        34Mi        84Mi       224Mi       114Mi
Swap:          14Gi       7.9Gi       7.0Gi
NAME       ALGORITHM DISKSIZE  DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram0 lzo-rle      14.8G  7.9G  1.9G  1.9G       6 [SWAP]

And the system is still surprisingly responsive for a low-power CPU.
