Another data point: on my RPi 3B+, I get this:

rpi% time freebsd-version -kru
13.0-RELEASE-p4
13.0-RELEASE-p4
13.0-RELEASE-p5
0.372u 0.053s 0:01.34 31.3%     27+178k 28+0io 0pf+0w
rpi% time freebsd-version -kru
13.0-RELEASE-p4
13.0-RELEASE-p4
13.0-RELEASE-p5
0.372u 0.047s 0:00.41 100.0%    27+174k 0+0io 0pf+0w

So it's not a general problem.
