[Bug 1869435] Re: Performance regression on ubuntu focal

[Balint Reczey]

@sergio-j-cazzolato I see the difference, but those operations are not
particularly time-critical.

Snapd restarting slowly can be investigated in snapd. Colord restarts
quickly on my laptop for example:

$ sudo time service colord restart
0.00user 0.02system 0:00.08elapsed 27%CPU (0avgtext+0avgdata 6948maxresident)k
3336inputs+0outputs (9major+1095minor)pagefaults 0swaps

Title:
  Performance regression on ubuntu focal

Status in systemd package in Ubuntu:
  Opinion

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
