15.0 and main port-package builder jails also are not based on
WITH_LLVM_LINK_STATIC_LIBRARIES= as stands.


So, should the (or some) official port-package build server jails for
15.0 and/or main (and, eventually, 14.4) be jails that are based on
WITH_LLVM_LINK_STATIC_LIBRARIES= ? Especially ampere2 for its
main-arm64-default builds (the most time consuming build context for
from-scratch bulk build runs as stands)? At least until the time
difference for dynamically link library use has been cut down noticeably?


Based on (normal-configuration) builds that started in 2026:
(ampere5 had an initial low-memory configuration based build of
150arm64-default starting on Jan-3 that I ignore here.)

ampere2:  237+ hrs to build 35496+ port-packages (plus 140+ failures)
(main-arm64, 32 CPUs)

ampere4/5: 79+ hrs to build 35739+ port-packages (plus 112+ failures)
(150arm64-quartererly and 150arm64-default, both amperes having 160 CPUs
each)

By contrast, 143arm64-* ampere4/5 builds:
(so: based on using a toolchain built using LLVM static library linking)
ampere4/5: 63+ hrs to build 35740+ port-packages (plus 101+ failures)
(143arm64-quartererly and 143arm64-default, both amperes having 160 CPUs
each)
