I have a CL implementing a loading optimization:
https://codereview.chromium.org/2282303002/

I used git cl try to run some perf bisects using run-perf-test.cfg

Here is one of them:
https://build.chromium.org/p/tryserver.chromium.perf/builders/mac_10_11_perf_bisect/builds/855

I talked with sullivan@ who said that the job was strangely producing no measurements, when I asked how to measure the change's impact.

Was I holding it wrong? The command I used to spin up the bisects was:
git cl try -b mac_hdd_perf_bisect -b mac_10_10_perf_bisect -b mac_10_11_perf_bisect -b mac_perf_bisect_builder -b mac_retina_perf_bisect -b win_perf_bisect -b win_perf_bisect_builder
