Linuxmint (ubuntu), when filling the RAM, even the cursor starts to slow down, is it supposed to be like that?

Question

Solid State Drives

Good day gentlemen!
Stands on a linuxmint laptop, 8GB z-ram RAM, SSD drive, core i7 processor.
I work a lot with sites and a lot of tabs in different browsers open. I read somewhere that with such work, z-ram saves a lot of memory, installed it and at the same time replaced the disk with an SSD.
Previously, there were brakes when reaching 6.5-7GB of memory, but not much. When I replaced ssd + z-ram (it just so happened that at the same time) and now when the memory is full, everything gets up for 5-15 seconds, then again everything flies to new brakes. What could be? I read on the internet but didn't find anything, or I searched in the wrong way...

Answer 1

Yes, that's how it should be.
This is the scourge of Linux on the desktop, and one of a thousand reasons why it will never be more than 0.2% common, as it is now.
The problem is known and manifests itself on all versions of the kernel, you can still try to copy some file during this, the system will generally stand up.
There is no solution and is not expected.

Answer 2

even the cursor starts to slow down, as it should be?

Of course.
You are using z-ram!
Well, the banal logic - you do not have enough RAM (because browsers with a bunch of tabs eat it like horses oats)
In order to somehow work, the system pushes unused data to disk (swapping) - and it works, albeit slower.
And here you put z-ram - corny reduce the amount of available memory.
T, you already lacked it, and then you reduced it even more.
And the system cannot force the data to disk, because you now have swap in RAM.
As a result, the system is busy shifting data from RAM to RAM in the hope of freeing up some space in RAM.
Brilliant solution!
A person tries to scoop water out of a bucket - he scooped up a liter of water with a mug, poured it back., and wonders why the water in the bucket does not become less.
Yes, by the way - it doesn't matter what OS you have.
With such actions, the result will be the same in any OS.

Answer 3

Of course.
You are using z-ram!

On the contrary, as I turned on z-ram, it stopped hanging. But in the end, I still added more memory so that it was, but only positive impressions from the memory.
