Title:
  Performance regression on ubuntu focal

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  Hello, I noticed that systmed is performin some tasks much faster in
  bionic than in focal,

  I created a script which iterates doing some operations and executed
  that on bionic and focal: https://paste.ubuntu.com/p/zWWQjndtXx/

  I see for example how systemctl daemon reload takes more time in focal
  even where there are less units than in bionic

  results:
  bionic: https://paste.ubuntu.com/p/z32WScydNk/
  eoan: https://paste.ubuntu.com/p/V98vd5CHwq/
  focal: https://paste.ubuntu.com/p/brNjKvC2gF/

  The tests was done in gce using clean instances type n1-standard-2.

  Please tell me if you need any extra info
