I'm very new to Ubuntu.

My PC has had very slow boot and shut down times (for 2 days), I reduced the shut down time with this tutorial (https://sites.google.com/site/installationubuntu/home/ubuntu-16-4-lts/make-slow-shutdown-faster) but PC still has some latency problem.

Using systemd-analyze blame from the terminal shows: 

17.990s NetworkManager-wait-online.service
 7.379s dev-sda1.device
 5.271s dev-loop0.device
 5.268s dev-loop1.device
 5.264s dev-loop2.device
 4.067s snapd.service
 2.015s postfix@-.service
 1.909s plymouth-quit-wait.service
 1.467s udisks2.service
 1.291s fwupd.service
 1.248s networking.service
  536ms accounts-daemon.service
  447ms tlp.service
  433ms ModemManager.service
  407ms NetworkManager.service
  357ms lm-sensors.service
  349ms keyboard-setup.service
  339ms preload.service
  339ms apparmor.service
  333ms grub-common.service
  333ms mono-xsp4.service
  312ms systemd-logind.service
  304ms apport.service

I think there is a problem but I don't know how to fix it.

Using one answer within Ubuntu 15.04 network manager causing slow boot worked for me:

systemctl disable NetworkManager-wait-online.service
