alt Hacker NewsIt takes a solid 45 seconds for me to enable zram (compressed RAM as swap) on a fresh Arch install. I know that doesn't solve the issue for 99% of people who don't even know what zram is / have no idea how to do it / are trying to do it for the first time, but it would be pretty easy for someone to enable that in a distro. I wouldn't be shocked if it is already enabled by default in Ubuntu or Fedora.

Zswap is arguably better. It confers most of the benefits of zram swap, plus being able to evict to non-RAM if cache becomes more important or if the situation is dire. The only times I use zram are when all I have to work with for storage is MMC, which is too slow and fragile to be written to unless absolutely necessary.
that just pushes away the problem ,it doesn't solve it. I still hit that limit when i ran a big compile while some other programs were using a lot of memory.
Zram has been enabled on Fedora by default since 2020:
