Long boot time, /etc/initramfs-tools/conf.d/resume not found

Question

After I mount a hdd I am finding relatively long boot time on ubuntu 20.04. On my PCI gen4 nvme, systemd-analyze

Startup finished in 10.499s (firmware) + 3.259s (loader) + 4.428s (kernel) + 8.384s (userspace) = 26.572s 
graphical.target reached after 8.379s in userspace

which sometimes goes above 31s!

My /etc/fstab looks like this.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/nvme0n1p2 during installation
UUID=db3bac2a-f735-4b0d-a6b4-dc99fdf1a60b /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/nvme0n1p1 during installation
UUID=F40C-278D  /boot/efi       vfat    umask=0077      0       1
/swapfile                                 none            swap    sw              0       0
###/dev/sda1    /work    ext4    defaults    0    1
UUID=531b1b74-891f-4f18-a288-cba9990bd31d /work ext4    defaults    0    0

However following Slow boot, long kernel load time, due to wrong resume device I tried to edit /etc/initramfs-tools/conf.d/resume which I could not find. When I created a file and followed rest of the advices, nothing improved.

I am completely confused to see conflicting information in various forums. Can anyone please help?

Edit 1: Random Information: sudo blkid | grep swap gave me no output!

sudo blkid0 gives the following output

I am using kernel 5.11.16, but please don't blame the kernel because my laptop on 5.12.rc5 with much slower nvme and cpu boots within 10s. — user43280, Apr 23 '21 at 08:11
I also do not have the resume file. That normally has the UUID of the swap partition. So I assume a swap file which I now have does not create that file. Some settings to reveiw: https://askubuntu.com/questions/1187117/slow-boot-boot-19-10-tried-almost-everything & https://askubuntu.com/questions/1018576/what-does-networkmanager-wait-online-service-do & https://askubuntu.com/questions/800479/ubuntu-16-04-slow-boot-apt-daily-service — oldfred, Apr 23 '21 at 14:18
None of them discusses about the missing conf.d/resume file? It's really bad. — user43280, Apr 29 '21 at 10:21
I still think something is wrong with my mounting of hdd or swap. — user43280, Apr 29 '21 at 10:22
Some users with lots of RAM do not have a swap, but one is recommended. You can add either a swap file or a swap partition. — oldfred, Apr 29 '21 at 12:25
