I have very recently learned about zram-swap. Fedora-29-arm is using it. It supposedly makes a considerable difference even over HD swap.
Do you have a link for me to read about that? I'd like to see some numbers on performance, specially on the CPU, because small ARM devices are not exactly fast to compress.
You could ask on the Fedora-arm list where Peter Robinson (I believe he is part of the Fedora development with heavy presence in the arm work) recently explained, kind of, how F29-arm is using it.
Since many (potential) users of Centos-arm do not have a ready HD, perhaps we can switch the image from a physical partition to zram? Or at least instructions to change to this on the wiki.
Switch might be difficult, but maybe generate a "tech preview" alternative build. This is the link to how we create the images, maybe you could send me some changes to test https://github.com/CentOS/sig-core-AltArch/tree/master/image_build
Minimally in the wiki, how to switch from a partition swap to zram. I am working on learning more about it...
