-Run the benchmark by executing the script:
-
-```
-bash ./buildbot-benchmark.bash
-```
-
-Collect "Real" time output from `time` output:
-
-```

-user    484m4.777s
-sys     42m40.285s

-
-Calculate seconds, rounding up decimals:
-
-```
-echo $((7*60 + 31))s
-```
-
-Input benchmark results under the "Speed" column in the [Buildbots](https://wiki.aosc.io/developer/infrastructure/buildbots/) page.
