And what are the benefits of using it?

zRAM is intended for using in those machines with 2gb or less of RAM, actually you'd get better results and/or see any performance improvement with 1gb of RAM. If you have more than 2gb of RAM it doesn't worth the time since you won't see much of a difference regarding performance, in fact, and according to what I've read,  you'd probably see a decrease of it.
Hope this helps!

Moltke a bunch of the computers I am working on have 2 GB RAM so given that the RAM is at the top end of the range “do I” or “don’t I” use zRAM to help performance..?

Thanks, Janet

My stats on 2.4 LL with firefox 57 and whole lot going on.
You won't have what I show as a command because I installed this manually. It is not a stock Linux Lite application.

Warning: Swap is not reported by this system.

See. I am not even close to the 2 gig of ram  on this laptop. I am not doing and video editing though. Just a normal Linux session for a normal beginner Linux Lite User session running Firefox and XFCE < tons of addons in my xfce session>

The swap message above is because I run a SSD drive out of a older apple computer and I don't trust the drive to last with swap enabled.
