Everything is slow , especially firefox!

Facing a lot of issues with speed.
Loading tabs , videos , whatsapp , etc is way too slow .

Plus even booting is slow. Even the default apps like setting take a lot of time to load.
I installed preload [today ] to make things a little fast , hope it helps the basic tasks

Because of these firefox issues i had to switch to opera but found out it has some legal issue with linux ,basically media doesn't work as intended so had to come back to firefox.

I don't know if i am doing anything wrong or it has something to do with the installation stuff.

Your processor speed of 1.6 GHz is a bit on the lean end. I am not convinced it is enough to create a definite slowness to performance.

First thing, please run in terminal:

sudo apt update && sudo apt upgrade

to make sure that everything is up to date.
That may help a bit.

You can use df -h in terminal to see if your disk is low on space. (I recommend running it to be sure of what is going on, since if there is a hardware issue with the disk, this can provide that clue.)

The next thing that comes to mind is Temperature. You can use psensor to monitor temps

sudo apt install lm-sensors psensor

Launch Psensor and monitor to see if your machine is overheating.

Have you tested a LiveUSB of Zorin OS Lite?

and i havent tested LiveUSB i dont have lite version btw
Thanks for helping out btw !

You added a Jammy Repository. Zorin OS 16 is on the Focal Repositories.

You can fix this by launching Software & Updates and moving to the Other software tab. Scroll through the list and select the MongoDB repo and then click the Remove button located on the bottom toolbar.

Everything there is normal... I do not see any disk-space issues.

None of these are in range to cause any major issues. They are normal.

You can download Lite from here if you would like to place it on a USB and Live Test it the way you did for installing Zorin OS Core.

Can you get more descriptive? "Slow" can be a subjective term. In seconds, how long does boot take?
How long does Launching Firefox take? Do Pages load slowly?

What is the slow OS startup compared to? If it is Windows, it is not a malfunction. Zorin OS does not have a feature like Windows' Fast Startup. Many Windows users recommend disabling Fast Startup because it causes trouble.

I restarted my pc just to record the timings

it took about 3 minutes to boot
then another 3 minutes to open firefox which loads the previous tabs and then come here

plus even when i started writing this reply there was high delay in typing
basically the whole browser or os was laggy after startup
slowly the lag reduced then stopped
after the initial laggy start it works rather fine

oh yes also i removed the mongo repo from Other Software


tho i am still getting this

What is your output for (the ls is L and S in lowercase, for list):

ls /etc/apt/sources.list.d

?
In your BIOS Settings, is Secure Boot disabled?

as for secure boot i will have to check

Run these to remove the mongodb repos:

sudo rm -rf /etc/apt/sources.list.d/mongodb-org-3.6.list

sudo rm -rf /etc/apt/sources.list.d/mongodb-org-3.6.list.save

sudo rm -rf /etc/apt/sources.list.d/mongodb-org-6.0.list

sudo rm -rf /etc/apt/sources.list.d/mongodb-org-6.0.list.save

For your 3 minute boot time, what is the output of

systemd-analyze blame

?

Is Firefox installed as a Snap package?

and firefox - i dont think so , tho is there a way i can check that
Thanks a lot btw !

You can check with:

snap list

You can check flatpaks installed with:

flatpak list

SnapD appears to be the biggest user of resources and time... This means the Snap Process Daemon and any packages...

I am not seeing any indication that anything is "wrong" - only that everything seems to be taking a lot of time.
From the current available information, I would try testing with SnapD disabled and see if you get any performance improvement.

sudo systemctl stop snapd.service

sudo systemctl disable snapd.service

Alrighty i disabled it !

Again thanks a lot !

You can reboot and the above disabling of snapd should persist. Test if you see any change or a bit faster speed.

For the record, you can reenable snapd:

sudo systemctl enable snapd.service

sudo systemctl stop snapd.service

If you need it or want to use Snap Packages.

should i remove / stop using snap as a whole ?
im fine with not using btop

I personally do not use either flatpak or snap. It's just a personal preference. I remove both, including the Software Store plugins. For this reason, I am often shielded from some of the effects of having those two on the system.

If you are seeing a good improvement in performance, I would recommend removing Snapd and all snaps - definitely.

Something interesting , Things are much faster now tho as far as firefox is concerned , first time opening firefox ,all the tabs in it after boot take decent time compared to opening it second / third time which opens and loads the stuff instantly.
I'm guessing this has something to do with cache
It wouldn't hurt to keep the laptop in sleep when I'm not using it

Only loading it first time is relatively slow then it works seamlessly
Other than that everything is perfect !
