I had installed Mycroft AI to test it but noticed it seriously slowed down my start-up boot. After uninstalling Mycroft AI, boot time is still slow. I had to update grub and it still slow. I ran "systemd-analyze time" in terminal and got the following results;

Startup finished in 3.800s (firmware) + 6.812s (loader) + 6.322s (kernel) + 43.748s (userspace) = 1min 684ms
GRUB TIMEOUT IS THE FOLLOWING
# Written by com.deepin.daemon.Grub2
GRUB_BACKGROUND="/boot/grub/themes/deepin/background.png"
GRUB_CMDLINE_LINUX_DEFAULT="splash quiet "
GRUB_DEFAULT="0"
GRUB_DISTRIBUTOR="`/usr/bin/lsb_release -d -s 2>/dev/null || echo Deepin`"
GRUB_GFXMODE="1366x768"
GRUB_THEME="/boot/grub/themes/deepin/theme.txt"
GRUB_TIMEOUT="1"

Userspace of 43.748s seems very heavy. I do not have many services starting-up and apps. My laptop specs are very descent;

I improved the time. I think I pushed it to its "limit". Considering getting an SSD for the laptop to get faster boot times.
