The builds outputs do not seem to be used anywhere.

https://ci.chromium.org/p/flutter/builders/prod/Linux%20Benchmarks%20%28no-upload%29:

Builds host_release and runs testing/benchmark/generate_metrics.sh which runs multiple binaries redirecting their outputs to files but nothing is being done with those files.

https://ci.chromium.org/p/flutter/builders/prod/Linux%20Benchmarks is building the engine release config, running the script and uploading the results to datastore in the flutter-cirrus project. Nothing seems to be reading the flutter-cirrus datastore.
