 |However, sometimes there is a delay of up to 2 seconds.

fwiw, only as an idea, postfix (at times -- do not ask me no
questions) needs to call the gethostname(3) function, which in
turn uses uname(2), and certain libraries / setups did, once
i looked last, try several things to fill in all members of this
struct (including non-portable extensions).
I had this hang also (very long ago), and placed in the manual of
the MUA i maintain this:

 One may have varying success by ensuring that the real host‐
 name and ‘localhost’ have entries in /etc/hosts, or, more generally, that
 the name service is properly setup – and does hostname(1)∞ return the ex‐
 pected value?  Does this local hostname have a domain suffix?  RFC 6762
 standardized the link-local top-level domain ‘.local’, try again after
 adding an (additional) entry with this extension.
