[Reproducible-builds] Performance of armhf boards

I was wondering what is the performance of various armhf boards, for
package building. Of course, the reproducible-builds team have a lot of
stats already. Below I'm sharing the query I used and the results in
case anyone else is interested in this.
$ DATE=$(date -u -d "1 day ago" '+%Y-%m-%d')
$ sqlite3 -column -header reproducible.db \
"SELECT r.node1 AS buildd, COUNT(r.id) AS pkgs_built, CAST(AVG(r.build_duration) AS INTEGER) AS avg_duration FROM results AS r WHERE r.build_duration!='' AND r.build_duration!='0' AND r.build_date > datetime('$DATE', '-$TIMESPAN_RAW days') GROUP BY r.node1 ORDER BY pkgs_built DESC"
Figures will vary based on which packages were assigned to which
node, as some are easier to build than others, but I hope over 21
days that variance is smoothed out.
Assuming the nodes had no downtime, we can compare pkgs_built over
the 21-day period to assess performance.
Also avg_duration is meaningful, but will increase where the
reproducible-builds network scheduled more concurrent build jobs on a
node. (Low avg_duration does not always mean high package throughput,
it may just be doing fewer jobs in parallel.)
Finally, the nodes' performance will depend on other factors such as
storage device used, kernel, etc.
Rows are annotated with number of cores, amount of RAM, and board.

I don't know whether to believe these figures yet!
* wbq0 is impossibly fast for just 4x1GHz cores, 2GB RAM...
* odxu4 looks slightly faster than the other two.
* cbxi4a/b seem no faster than cbxi4pro0 despite twice the RAM?
* ff2a/b show USB3 SSD to be no faster than USB2?
* bbx15 may be able to handle more build jobs (low avg_duration).
* bpi0 may be overloaded (high avg_duration).
* ff4a maybe had downtime, and seems to be under-utilised.
* rpi2b maybe had downtime, or has a slower disk than rpi2c.
* wbd0 slowness is likely due to the magnetic hard drive.
Corrections/suggestions are welcome.
Many thanks to Vagrant for hosting all these armhf nodes!
