@sergio-j-cazzolato I see the difference, but those operations are not particularly time-critical. Snapd restarting slowly can be investigated in snapd.

[Touch-packages] [Bug 1869435] Re: Performance regression on ubuntu focal
Hi, In our tests logs we see that focal is slower than other systems like bionic. I printed all the commands we run with the times and noticed the main diff on times is when running different systemd commands. So I did a very small script to compare basic calls that we use in our snapd test suite. Now I did a new comparison between focal and bionic but changed the paramenters compared with the previous logs, now I am using the calls we see in our tests which are slower on focal compared with bionic. script used: https://paste.ubuntu.com/p/JG977dRXMy/ results bionic: https://paste.ubuntu.com/p/GDfnwMMTF2/ results focal: https://paste.ubuntu.com/p/GDfnwMMTF2/ All the results are in milliseconds. With these logs I think is more clear the performance difference between both, i.e. "systemctl list- unit-files --full" taks almost the double on bionic than focal. Does it make sense? Do you need more info?

[Touch-packages] [Bug 1869435] Re: Performance regression on ubuntu focal
Those units are milliseconds. And the focal times for restarting snapd are actually better than bionic or eoan. I'm not sure what exactly you want done? ** Changed in: systemd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1869435 Title: Performance regression on ubuntu focal Status in systemd package in Ubuntu: Incomplete 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.
