OK, so it's a normal unix release, and uses proot for a virtual directory structure. It says it only uses the terminal emulator from termux.
termux doesn't use proot - its distribution has all paths rewritten (usually in source) to cope with the android filesystem (and other changes). I'm always surprised that this hackery works so well!
Therefore, I'd expect identical programs to be slower in nix-on-droid.

Probably. But modern phones are well beyond the power needed to run linux programs at useful speeds. Termux first came out over a decade ago, IIRC. Back then phones were much less powerful.
