The only standout is rngd.service. That's a pretty big single hit,
percentage wise. And I don't know if we even need it anymore. Among
the rest, perhaps atd.service and crond.service could be disabled by
default on new installations, in favor of systemd timers.
Well, what rngd does is highly system dependent, and in a VM it's gonna
depend to a degree on exactly how the VM is configured (whether you
attach some kind of virtual hwrng to the VM and if so how it's set up
exactly). You'd want some data from real systems and probably different
VM configs before deciding rngd is a big problem.
