"Sample size of one," but a possibly-interesting comparison

My build machine tracks head, as well as recent stable (since 12 was
branched, stable/11 and stable/12), running a GENERIC kernel to do so.
As described in <http://www.catwhisker.org/~david/FreeBSD/upgrade.html>,
each of the three branches boots from its own slice on the same physical
machine; the boot drive is an SSD.

On weekends, it also uses poudriere to build local packages for
installation on my "production" machines during their weekly updates
(Sunday morning).  Since the end of October, these poudriere runs have
included stable/12 (as well as stable/11).

After finishing the poudriere run from stable/12, I notcied that its
summary output showed that the same number of packages had been built as
for stable/11 -- not surprising, of course.  A further check showed that
the same set of packages was built in each case, so I thought I'd share
this mini-comparison as a bit of a reality check:

[11amd64-ports-home] [2018-12-29_11h44m22s] [committing:] Queued: 106 Built: 106 Failed: 0   Skipped: 0   Ignored: 0   Tobuild: 0    Time: 01:06:00

[12amd64-ports-home] [2018-12-29_13h02m24s] [committing:] Queued: 106 Built: 106 Failed: 0   Skipped: 0   Ignored: 0   Tobuild: 0    Time: 01:05:31

I don't suggest drawing many conclusions from this, except perhaps
to note that in this environment, stable/11 and stable/12 seems to
be roughly comparable at first glance (both in ability to build the
packages and in performance).

as dmesg output, may be found at

Beyond some threshold, should presidential lies become impeachable offenses?
