In current configuration where I "target" benchmark run to around 200ms
(thus possibly jumping up to 400ms) and thus 1-2 sec for 3 actual
runs to figure out min among those -- on that elderly box it takes about
a day to run "end of the day" commits (iirc around 400 of them) and then
3-4 days for a full run (all commits).  I am not sure if targetting
200ms is of any benefit, as opposed to 100ms which would run twice
faster.

you are welcome to give it a shout right away

it is still a bit ad-hoc and I also use additional shell wrapper
to set cpu affinity (taskset -cp 1) and renice to -10 the benchmarking
process.
