I have just 20 pages opened in 3-4 browsers windows (chrome and firefox) and Videolan running some audio streams or video and system is really choking, lots of scatterings, jams. I'll try the 5.3RC2 kernel and revert back to 5.1 kernel if this newest won't solve the issue, but there's definitelly some issue, even I tried to build some package from AUR which in past went more quickly and with less resources usage now it seems to lasts forever so I need to hard reset the laptop (8 thread intel i5-8250U, 8GB RAM)
Without more information, it's hard to know where to start with help. Please provide more information.
Emphasis with bold is mine...
Are you at all surprised that the system chokes on that? Your system is constantly swapping, and the I/O to and from your swap partition is blocking everything else.
If you want to keep doing that kind of stuff, then you should upgrade your RAM to at least 16 GiB or perhaps even 32 GiB.
5.1 is EOL. It is no longer in the repository.
The observations are valid if this happens only with kernel 5.2. If the symptoms don't persist with 5.1 or 5.3rc then it's something in kernel 5.2 (to which the solution may well be "use a different kernel").
@jonathon, I have 8 GiB of RAM too ─ and 6 actual cores ─ and if I have 3 to 4 browser windows open with 20 tabs, then my system will be swapping too, regardless of what kernel I'm using.
As the matter of fact, even with
vm.swappiness=0, I've got 1.3 MiB worth of swap in use right now, with only Google Chromium, KMail, Claws Mail (for Usenet) and one Konsole window open. And I have on average 6 to 10 tabs open in that single Chromium window. Not 4 separate browser windows, not 20 tabs and no VideoLan streams.
And when I was compiling the appmenu-enabled version of Firefox from the AUR, my system was locked up solid for 5 hours straight, with all cores maxed out, all of my 8 GiB of RAM in use, and about 8 GiB worth of swap.
There's only so much the machine can take, you know.
Can we see the output of these commands:
inxi -Fxxxza swapon -s
Which package were you trying to build?

the package to built is
mongodb-compass-beta 1.19.0beta.2-1 or other mongodb it was and I then found already compiled
mongodb-bin package from AUR and I probably switched to that instead of waiting to compilation being finished...anyway a painfull process, more than 2 hours and still no finish...
I've tried experimental 5.3 kernel but was already some choking ongoing from the start when the system was loaded and even I couldn't connect to my wifi after typing password (I was redirected to endlessly type the password without the connection being established) so I reverted back to 5.2 kernel and have installed but inactive 5.1 version just in case.
I have no any programs opened and with 5.2 kernel some weird things happens and this choking effect occurs from time to time and it was never like that even with lots of web pages opened or multiple browser windows. I could have chrome, firefox, krita/gimp/inkscape, vlc and some other lite apps opened at the same time with no any issues with efficiency. But now it seems weird vulnerable to use more than a few things or any.
There's no point in spending any more time describing the issue you're having with 5.2.4.
If you're not going to try other kernels (or even update to 5.2.6 via the testing branch) to try and narrow down the issue then any more discussion is pointless.
In addition to trying kernel 4.19 as @jonathon suggests, check to make sure baloo isn't compounding your issues with
balooctl monitor If baloo is reindexing, that will slow everything down. With your spinning disk and heavy workload, that could put you over the edge.
I was fine without any issue with Kernel 5.x, just recent changes in kernel brought the possible issue as I didn't change anything in system
Just because the kernel changed doesn't mean nothing else changed. Sometimes baloo will start re-indexing after a reboot.
That being said, it is easy enough to test. Make sure your system is up-to-date and switch to kernel 4.19.
5.0? 5.1? 5.2? They are very different kernels, and each series has numerous sub-releases.
