I had similar effects on Ubuntu after update from kernel 5.0 to 5.3. Effects appeared as soon as system started to use swap (it did not matter what amount, even several MB was already enough). Same was with kernel 5.4, I ended up using kernel 5.5.
Interesting. With openSuse 15.2. my problems with swap have finally been solved. I was struggling since the 13.x-series.
This is very interesting. In my experience, swap changed to the bad from 13.x to Leap. I don't have any 15.2 yet to compare. I called the issue "swap fragmentation". The hard disk was constantly seeking to locate the areas to read or write on swap. My solution was to buy an SSD and put swap on it: besides the increased read/write speed, the seek time is basically nil, so there is no fragmentation penalization. Now all my working machines are on SSD, so I will not be able to check if this "fragmentation" has been solved on 15.2. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
