FYI: main-arm64 port-packages built per Hr. on ampere2, some history and comparisons/contrasts

Start time then built/approx.Hrs approx.= ratio

I tried to avoid examples of incremental builds
and of large scale build failures.


ampere2: (so debug-build for each of boot-kernel,
          boot-world; main-arm64 so debug-build of
          jail-world)
01 Mar 2025 01:34:16 GMT	34828/162.0 approx.= 215.0
11 Mar 2025 01:30:33 GMT	34853/163.3 approx.= 214.4
01 Apr 2025 01:31:49 GMT	34856/508.0 approx.=  68.6
06 May 2025 02:47:25 GMT	34892/458.3 approx.=  76.1
14 Jun 2025 02:48:40 GMT	34596/390.3 approx.=  88.6
19 Jul 2025 01:09:55 GMT	34787/406.3 approx.=  85.6
19 Aug 2025 13:44:37 GMT	35240/506.5 approx.=  69.6
19 Oct 2025 16:25:18 GMT	35244/235.3 approx.= 149.8

(I ignored Failed builds. The detailed ports tree
content also varied. As did the detailed boot kernel,
boot world, and jail world. Also: pkg versions varied.)

Such builds of main-arm64 on an ampere are the most time
consuming generally.


150releng-arm64 has a default (latest) and a Quarterly
comparison/contrast available. Quarterly is from
ampere3 instead of ampere2. default is from ampere2.

ampere2 (150releng-arm64 so non-debug jail world):
12 Oct 2025 03:38:25 GMT	35356/180.8 approx.= 195.6

At this point 15.0 and main are not all that different,
but, for example, the jail world for main is a debug build
on ampere2 but 150releng-arm64 is not.

ampere3 (so non-debug for each of boot-kernel, boot-world;
         150releng-arm64 so non-debug jail-world):
12 Oct 2025 02:29:30 GMT	35601/177.9 approx.= 200.1


There is one 143arm64-default (latest) from ampere3 that
is available as well:

ampere3 (so non-debug for each of boot-kernel, boot-world;
         143arm64-default so non-debug jail-world):
19 Oct 2025 12:21:31 GMT	35415/150.4 approx.= 235.5
