I suspect, Docker has its overhead. Apart from downloading the Docker
image (is it cached? who knows), setting it up for testing usually
requires installation of more packages. Furthermore, I'm not sure if
that package downloading is backed by GHA cache (probably not), which
means you're pulling packaged from Ubuntu repos instead of the GHA local
cache, which is configured in the GHA images. I don't need to remind you
that network issues often cause spurious CI failures, which means the
less network activity the better.
