(In reply to Mark Millard from comment #5)
[I should have mentioned that the ThreadRipper
results are based on non-debug builds of main
(14-CURRENT). So are the below. Same FreeBSD
vintage (same source tree even). UFS2+SU (no J)
again as well.]
aarch64 examples that others might be able to
compare against . . .

The "rm -fr" here took a larger fraction of the
"make extract" "real" time compared to the
ThreadRipper ratio.
A MACCHIATObin Double Shot got similar results
(4 Cortex-A72 cores, 16 GiByte RAM):

Of course, the SSD's involved are not likely to
be as subject to fragmentation consequences as
spinning drives. So comparisons to the above
might be complicated by such.
(There may be better things to look at with
other tools.)
