Builders:
https://ci.chromium.org/buildbot/chromium.perf/Android%20Nexus5X%20WebView%20Perf/
https://ci.chromium.org/buildbot/chromium.perf/Android%20Nexus6%20WebView%20Perf/

There is the step of uploading to test results server here: https://logs.chromium.org/v/?s=chrome%2Fbb%2Fchromium.perf%2FAndroid_Nexus5X_WebView_Perf%2F2140%2F%2B%2Frecipes%2Fsteps%2FUpload_to_test-results__performance_webview_test_suite_on_Android_device_Nexus_5X_%2F0%2Fstdout
