Ubuntu 20.04 webserver
Platforms : Webmin/Virtualmin
Hardware: i5-4570 + 8gb ram and 1 SSD
I had installed OpenMediaVault at some point on server and i purged it and removed ssd with the openmedia vault.
I think boot time is affected by this.
Here are some commands from logs:
systemd-analyze time
Results:
Startup finished in 5.827s (firmware) + 2.794s (loader) + 3.302s (kernel) + 1min 40.095s (userspace) = 1min 52.019s
