I always cared with ZRAM under GNU/Linux (I own an n270 netbook with 1GB of RAM and a NUC with 8GB but a Pentium Silver CPU, nothing fancy). Thus, Waterfox with their new Rust based ad blocking engine was a beast, even more with WebGPU enabled and NoScript, just enabling JS for the essential, if any. On top of that, the tab suspending extension. As I program in Rust I need every bit of RAM, even if I disable most debugging options at ~/.config/cargo.toml and I set the build jobs to 1 with "-j1 ".

On the netbook, well.. CWM, UXterm, Dillo, CLI/TUI mail, usenet, IRC and so on clients, groff, nsxiv, mpv, MuPDF... it runs snappier than the NUC for what it does. Programming? Golang for networking stuff -security, not like Rust, but far better than C-, simple C99 for small software, or S9/JimTCL. Otter Browser for emergencies (JS pages from public institutions/govts in my country).
