The typical boot-up time of my Ubuntu VM on Hyper-V is 20~30 seconds for a Desktop version of Ubuntu, and 10~20 seconds for a Server version. I tried Ubuntu 19.04 just now and it also took 20+ seconds.
I never achieve a boot-up time of 2s.
I do know Ubuntu can boot up fast in 2~3 seconds in WSL (Windows Subsystem for Linux), though I didn't try it in person.
