[Bug 1869435] [NEW] Performance regression on ubuntu focal

[Sergio Cazzolato]

Public bug reported:

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
