When few number of programs are opened, the system keeps lagging and te system hangs, with high CPU usage shown in System Monitor and nohang notification keeps popping up.
Here's a screenshot of applications open and cpu usage.

I applied a swap of 4GB won't that work? My ram is actually of 8 gigs but 2 is used by integrated graphics
Take 16 GB its fast (ID-1: /dev/nvme0n1) but I am not an expert for this.

I noticed that whatever is the usage of ram and swap (even at the extremities like the aforementioned) it never exceeds 5.7GB which is my ram capacity i.e.I am assuming the swap memory is never used. Is that so? And also the Stats in the System monitor shows my ram is 5.7 and swap is 9.7(i.e. 5.7+4) is this normal?
Yes, we use zram for cpu

A Gaming Laptop with less RAM (and -2 GB for GPU) is really …
If possible buy RAM, BIOS seems fresh, how old is the Laptop?

Yes the RAM for a Gaming laptop is just minimal , the laptop is 4 months old.

What happens when you run fewer applications?
6GB RAM is not very much now - just a browser with a few tabs open will easily use 2-4GB.

When running fewer apps it works fine without any issue

So I guess the issue is with the ram capacity.....
Yup - you're seeing the result of running out of RAM and how Garuda uses ZRAM rather than plain swap.
Normally, your PC would slowly grind to a halt as memory was swapped to the disk-based swap file. Disks are slow (even SSDs) compared to RAM.
With how Garuda uses ZRAM, memory is compressed to try and avoid writing to disk. It's definitely faster than swapping to disk, but will use a lot of CPU if it's being used heavily.
Without swap, your PC would simply freeze (or crash, depending) when it ran out of available RAM (which is why having some swap is generally a good idea).
Unfortunately there's only two real solutions to not having enough RAM:
- run fewer applications
- buy more RAM

Thanks a lot for pin pointing the reason and the solution @SGS @jonathon, and yes this btrfs, zen linux and zram and not forgetting to mention the best part - the overall UI of the dragonzed version is the reason for me shifting to Garuda from stalk Archlinux running alongwith KDE Plasma, love the overall performance

Perhaps Xfce or one of the Window Managers may provide you better efficiency? The available artwork, theming, etc., while not quite as stylized as @dr460nf1r3’s release, might fill some of those holes while not running on your resources razor’s edge?

Yes this does the work thankyou @Bro but with limited scope as opening a few more tabs in browser or apps reinitiates the problem as ram gets filled up

Yeah, the thing with Garuda is it is built to sacrifice RAM to increased optimization + services. It really demands a higher amount of RAM to provide the most efficient usage of the system. But, hey, it shouldn't be difficult to add a bit more, assuming it is in your budget at this time. I note the 12 gigs on my desktop machine and the 8 gig laptop both run efficiently.
If that is not the case, perhaps you might be able to eliminate say, unneeded systemd services?
And, as someone else already stated, even in cases where RAM is nearly/fully consumed, Garuda is built to handle OOM problems in a more elegant manner than your run of the mill distribution. I tell ya, these folks know how to make a hip 'n' slick distro.

A new 8gb ram is affordable for me rn, but the problem is that my laptop's ram are placed in dual channel, thus blocking both the slots with 4 gigs each. For upgradation I have to discard one stick for the new one . Dont't know what to do of the old one.
