zswap and zram are fundamentally different approaches with different philosophies. If in doubt, use zswap.

    More or less.

    • Zswap is better than zram because it’s integrated with the kernel. Swap in zram is more of a hack.
    • zram can kill your file cache unnecessarily, which leads to more disk reads.
    • Don’t use zram without an oom killer.
    • They’re working on zswap to not require any disk swap at all, basically killing the last reason why one might want to use zram over zswap.
