Comment # 36 on bug 1159882 from Robert Delahunt

http://www.puresimplicity.net/~delahunt/vmstat/cgroup_disable/

Here are some vmstats for the stock OpenSUSE LEAP 15.2 kernel.  I started the
dd command then realized I don't have a swap set, so I created one and added
it.  As soon as I ran swapon, it climbed to about 20MB or so.  Still a bit
better than the excessive swapping, but still, with 16GB of main RAM and
nothing but Chrome running, that's excessive.

Let me know if this is enough or you want me to install the latest kernel.  I'm
very eager to help.
