And there is another issue, of which I have no hard proof: swap suffers of fragmentation and consequently more disk head movement in Leap compared to 13.1
That could be it. :-\
I installed an SSD disk and the issue improved dramatically. After two years or so I bought another computer, but it is still waiting for assembly in the table behind me. So the SSD bought me some years of time.
One other thing, the heavy disk activity is on an occasional basis. It can go hours without it happening, with the computer running find the rest of the time. For example, right now it's running 13.5 GB of memory and 4.4 swap. Yet, the computer is properly responsive. I just fired up a couple more Firefox windows and I don't notice any difference in response. So, I'm thinking it's something other than swap, that occurs at long time intervals.
If "top" at the moment shows "free" to be way less than 1G, like it did the second time, when you posted:
Here's another capture. I see X is high again and I had a lot of disk activity.
Tasks: 263 total, 1 running, 262 sleeping, 0 stopped, 0 zombie %Cpu(s): 3.3 us, 2.9 sy, 0.0 ni, 80.6 id, 13.1 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 15923.24+total, 430.297 free, 14000.02+used, 1492.918 buff/cache MiB Swap: 16383.68+total, 15117.98+free, 1265.699 used. 847.727 avail Mem
That moment the problem was trashing. If currently you have four GB in swap, be assured that _your_ system needs it now and works better with it. -- Cheers / Saludos, Carlos E. R. (from oS Leap 15.0 x86_64 (Minas Tirith))
