It is useful, unless you have an absolute crapton of memory, several times what you actually need. The swap is trivial to encrypt if you're paranoid (the key doesn't need to be persisted and can be generated from /dev/urandom on each boot). https://chrisdown.name/2019/07/18/linux-memory-management-at-scale.html https://chrisdown.name/2019/07/18/linux-memory-management-at... https://haydenjames.io/linux-performance-almost-always-add-swap-space/ https://haydenjames.io/linux-performance-almost-always-add-s... https://wiki.archlinux.org/title/Dm-crypt/Swap_encryption https://wiki.archlinux.org/title/Dm-crypt/Swap_encryption

absolute crapton of memory, several times what you actually need Err, you mean every rack-mount system since around 2000s? Seriously, the commissioning overhead for virtually anything exceeds the "max out the ram" tax. Unless you're a cloud provider commissioning autonomously and operating at excessive scale seeking some particular unit cost optimization ... and even then not maxing out RAM (to some current definition of effective price:performance maxima) would be odd.
