[kwlug-disc] zRAM on older machines?

[Charles M]

I'm wondering if anyone on the list has been using zRAM on older
hardware (Intel 3rd to 6th gen)? I was looking into it recently
thinking it might be beneficial for some of the older systems we
rebuild in CR. The pitch for it seems to be that it:

Helps reduce wear on SSDs
Reduces lag & freezing on older systems
Can improve performance on slower devices (I didn't notice a
difference in boot times on a 3rd gen with 8GB and a 2.5" SSD in my
testing)

I was a bit confused when it came to the claims around out of memory
situations, I saw info that suggested it helped with OOM, and info
that suggested it contributed to OOM (which seems to be the more
likely since it's in RAM)

Does enabling zRAM cause issues with systems that are put to sleep?
What about conflicts with tools like tlp (ThinkPad)?

Does anyone have zRAM configured on their laptop/desktop?

Cheers,
