Today:
"""
$ time t/runtests --dump-logs -k t debian/test-out suite:tests -j4
[...]
real 5m56.967s
user 15m38.488s
sys 4m6.696s
"""
These timings are from my laptop (and not my "heavy-duty" build machine,
which was used in all my other benchmarks). The timings were obtained
by using the new test-artifact caching in t/runtests. The run building
that cache was sadly still horribly slow, but at least it is (mostly) a
one-time price now.
I will consider this as good as it gets for now and close this bug in
2.5.21.
