Using 5.4.0-17.21-generic, my laptop has 16G of ram. If I launch 3 vms
(xenial desktop (768M), bionic desktop (1.5G) and focal desktop (2.6G))
then load this page: https://people.canonical.com/~ubuntu-
security/oval/com.ubuntu.xenial.cve.oval.xml, at some point while the
page is loading, the desktop interactivity degrades. top tells me I am
swapping 2.5G. (I have other tabs open in firefox of course). Eventually
the system settles down and interactivity is decent again.

Title:
swap storms kills interactive use
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hello, several times since upgrading to focal from 19.04 I've found my
computer entirely unresponsive for periods of twenty or thirty
seconds. No mouse movement, no keyboard input, the screen output does
not change.
My computer was using swap space and despite very slow writeout speeds
well below what the NVME drive can handle, the computer was unusable.
I've captured some vmstat 1 output and top output that I started
collecting during the event. (Normally one very long painful period is
followed by several shorter periods of uselessness.)
Thanks
