I use zram rather than a regular swap partition on all my laptops (because I'd rather not swap on SSDs) and desktops (same reason and/or there is an absurd amount of RAM to begin with). I also hear that most chromebooks use zram too (you really don't want to be swapping on that eMMC memory).

I set it up with one zram device per CPU core for a total space of ~20% available RAM.

No performance issues w/ zram so far so I haven't felt the need to change the compression algorithm.
