I feel like it started recently (last 3 months). I have Ubuntu 18.04 LTS on Dell XPS i7 with 16 GB RAM.
Linux 5.3.0-28-generic #30~18.04.1-Ubuntu SMP Fri Jan 17 06:14:09 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
total used free shared buff/cache available Mem: 15G 12G 1,0G 991M 1,4G 1,0G Swap: 19G 1,8G 18G
Where there any big changes to kernel/swap behaviour in last few months? Is there anything i can change or test some other settings?
(I need 20 GB of swap, as sometimes I run Docker with many containers.)
