Maybe Ubuntu inherits from Debian to perform security updates automatically at startup. On my Laptops running Debian and SparkyLinux this slowed down the startup between 20 and 60 (!) seconds, because it could only be accomplished when network connection was up and repository server answering. As I am anyway daily checking for updates (manually), I disabled this behaviour and gained that even my 10 year old Laptops (with their old HDD) have startup times of only between 30 and 45 seconds (kernel startup around 6 sec, userspace around 30 sec, according to systemd-analyze).
Instead of testing with a fresh Ubuntu installation maybe first tune it at least a little bit, if Ubuntu herited the above mentioned from Debian:
