Ever since I increased disk space on UBUNTU 18.04, the booting time has increased manifolds.I created new swap partition. As pointed out by other answers for similar question, I have Updated the UUID in /ext/fstab.
systemd-analyze time on terminal and the output is as follows:
Startup finished in 5.395s (firmware) + 6.836s (loader) + 4.535s (kernel) + 52.819s (userspace) = 1min 9.588s graphical.target reached after 49.244s in userspace
graphical.target @49.244s └─multi-user.target @49.244s └─kerneloops.service @40.919s +26ms └─network-online.target @40.913s └─NetworkManager-wait-online.service @32.043s +8.869s └─NetworkManager.service @27.622s +4.420s └─dbus.service @27.316s └─basic.target @27.312s └─sockets.target @27.312s └─snapd.socket @27.249s +62ms └─sysinit.target @27.249s └─cryptsetup.target @26.626s └─systemd-ask-password-wall.path @2.985s
That 52.819 sec is unusual. I have searched over internet many times but nothing seems to resolve this issue.
