Effective compression ratio is 3:1. Also, that's at the low end of
what I regularly see. High end 4:1.

I don't know how to interpret the above to come up with a compression ration.

When I first boot the system with no GUI login I see below after an ssh to the system.

[egreshko@f33g ~]$ uptime ; zramctl
17:50:18 up 0 min, 1 user, load average: 1.89, 0.55, 0.19
NAME       ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram0 lzo-rle       1.2G   4K   74B   12K       1 [SWAP]

A bit later on I login from the console and start a gnome-terminal session

[egreshko@f33g ~]$ uptime ; zramctl
17:56:13 up 6 min, 2 users, load average: 0.63, 0.45, 0.23

/dev/zram0 lzo-rle       1.2G 137M 42.9M   46M       1 [SWAP]

And after doing sudo dnf --refresh check-update later on, I now see

[egreshko@f33g ~]$ uptime ; zramctl
18:09:41 up 20 min, 2 users, load average: 0.07, 0.04, 0.09
