Thanks! Anticipating spikes in the graphs...

Ah, looking at:

  https://tests.reproducible-builds.org/reproducible.html

env DEB_BUILD_OPTIONS   DEB_BUILD_OPTIONS="parallel=XXX" DEB_BUILD_OPTIONS="parallel=YYY"
                        XXX for amd64: 18 or 17   YYY for amd64: 17 or 18 (!= the first build)
                        XXX for armhf: 4 or 2     YYY for armhf: 1 or 3

I guess it must just use the number of CPUs for first build, and number
of CPUs-1 for the second build (at least on armhf)?

Just added bbx15, a dual-core with 2GB of ram (and relatively fast
cpus), not sure where to fit that in the picture. Maybe 4 or 5 jobs
would actually be appropriate.

And thanks for maintaining the other side of the infrastructure! :)
