I have a Dell Latitude 6440 -intel i5-4310 laptop, 8GB RAM disk – SSD.
System on SD card – Ubuntu Mate 18.04.3 kernel 5.2.8. with encrypted partition / home.
This is what system-analyze looks like:
Startup finished in
8.807s (firmware) + 30.926s (loader)
+ 3.776s (kernel) + 32.108s (userspace)
= 1min 15.618s

graphical.target reached after 32.101s in userspace

What is it responsible for and what is the loader + 30,926s ?
How to speed it up?
$systemd-analyze critical-chain
The time after the unit is active or started is printed after the “@” character.
The time the unit takes to start is printed after the “+” character.
