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?
