Can confirm this is also happening with a Clevo N850HK1 (an Optimus-powered i7-7700HQ + GTX 1050Ti laptop).

It's hard to provide Solus-accurate benchmarks considering it's really hard for an average user to get it to work right now (no zram module in /lib/modules/(version)/kernel/drivers at all).
I've been able to find this kinda old thing though. I don't know whether zRAM is a thing that should be enabled for everyone, but it really is a life-saver for low memory PCs, because it only sacrifices a bit of CPU power.
Wouldn't it be a better option to, at least just for now:

Many games on Solus are unplayable without zRAM on machines with little amount of RAM (computer literally hangs).
I don't want to move back to Arch, please consider adding this soon :(
