Build time measurements

[Andreas Gustafsson <gson%gson.org@localhost>]

Hi all,

In September and November, I reported some measurements of the amount
of system time it takes to build a NetBSD-8/amd64 release on different
versions of -current/amd64.  I have now repeated the measurements with
a couple of newer versions of -current on the same hardware, and here
are the results.  The left column is the source date of the -current
system hosting the build.

  HP ProLiant DL360 G7, 2 x Xeon L5630, 8 cores, 32 GB, build.sh -j 8

  2016.09.06.06.27.17    3930.86 real     15737.04 user      4245.26 sys
  2019.10.18.17.16.50    4461.47 real     16687.37 user      9344.68 sys
  2020.03.17.22.03.41    4723.81 real     16646.42 user      8928.72 sys
  2020.03.22.19.56.07    4595.95 real     16592.80 user      8171.56 sys

I also measured the same versions on a newer machine with more cores:

  Dell PowerEdge 630, 2 x Xeon E5-2678 v3, 24 cores, 32 GB, build.sh -j 24

  2016.09.06.06.27.17    3321.55 real      9853.49 user      5156.92 sys
  2019.10.18.17.16.50    3767.63 real     10376.15 user     16100.99 sys
  2020.03.17.22.03.41    2910.76 real      9696.10 user     18367.58 sys
  2020.03.22.19.56.07    2711.14 real      9729.10 user     12068.90 sys
