On a laptop I have, a Thinkpad T410, i5 4 core 2.6GHz, 4G RAM,
Spinning 1 TByte 7200rpm disk (110 MBytes/s sequential reed
speed) I get the following rough figures:
Windows7 to login screen: 24s Windows7 from login screen to
desktop: 10s Windows7 overall: 34s
Fedora25/KDE to login screen: 50s (1:46 when updatedb runs)
Fedora25/KDE from login screen to desktop: 50s Fedora25/KDE
overall: 1:40 (-> 2:36 when updatedb is running)
I get similar but slightly faster speeds on desktop i5 systems,
again with spinning disks. SSD systems I have are faster (It does
seem to be disk bound) but still not that quick.
It is starting to get noticeable/an issue these days and getting
embarrassing when going to meetings with a Linux Laptop !
On my i7 desktop (booting from SSD) it's typically under 10
seconds from BIOS to login screen.
Maybe try "systemd-analyze --blame".
In fact "systemd-analyze critical-chain" is probably more useful.
I get this result...
root@nellie 13:26:58 ~ # systemd-analyze critical-chain
