I can't see anywhere in the article where it says which version of linux this was tested on (beyond "2017"), which is a shame.
Is this the state of affairs after the improvements described at https://lwn.net/Articles/724307/ have gone in?

> All tests were run on both ubuntu 17.04, 4.10.0-37, as well as on arch, 4.12.8-2. We got the same results on both machines.
That LWN article was from June 2017 and 4.10 was released in February, so I think that means these tests predate any of the changes it discusses.
