Let’s see: you create a process to run sudo, which does privilege checks 
and creates a process to run su, which runs privilege checks and spawns 
your actual command.

I just checked, and for some reason sudo itself needs two processes to do 
its stuff. So that’s *three* processes, not including your actual command.
