The Register contrasts zram and zswap. It flags a patch that claims up to 50% faster zram ops. It notes Fedora enables zram by default.
It details that zram provides compressed in‑RAM swap (LZ4). zswap compresses pages before writing to disk and requires on‑disk swap.
Distros and OSes ship memory compression by default. Swap shifts toward compressed in‑RAM tiers. Admins face revising swap layouts.
