Top on linux shows kernel threads (all the processes in square brackets), on BSD it doesn't show these afaik. A fresh debian install only lists a handfull of processes (all the expected ones, ssh, systemd, ntp, gettys etc) besides the 200+ kernel-threads.

Your right, you can show the system-processes in top with Shift+S, threads with Shift+H

Uh, ok then. I always thought that those were actually real kernel processes. What's the use of having top report those kernel threads? Is it possible to renice them?

Linux views them all as tasks, and yes you can (although I don't know if top does that).

Just a different "flavor"-default-setting of top, there's not much more behind it.
