<h3>Telemetry benchmark</h3>
<ol>
<li>Run <code>v8.browsing</code> benchmarks:
<pre>$CHROMIUM_DIR/tools/perf/run_benchmark run v8.browsing_desktop \
--browser=exact --browser-executable=$CHROMIUM_DIR/out/release/chrome \
--story-filter='.*2020 ' \
--also-run-disabled-tests
</pre>
</li>
<li>Install <a href="https://stedolan.github.io/jq/">jq</a>.</li>
<li>Convert the telemetry JSON files to callstats JSON file:
<pre>
$V8_DIR/tools/callstats-from-telemetry.sh $CHROMIUM_DIR/tools/perf/artifacts/run_XXXX
</pre>
</li>
<li>Load the generated <code>out.json</code></li>
</ol>
<h3>Merged CSV from results.html</h3>
<ol>
<li>Open a results.html page for RCS-enabled benchmarks</li>
<li>Select "Export merged CSV" in the toolbar</li>
<li>Load the downloading .csv file normally in callstats.html</li>
</ol>
<h3>Aggregated raw txt output</h3>
<ol>
<li>Install scipy, e.g. <code>sudo aptitude install python-scipy</code>
<li>Check out a known working version of webpagereply:
<pre>git -C $CHROME_DIR/third_party/webpagereplay checkout 7dbd94752d1cde5536ffc623a9e10a51721eff1d</pre>

<li>Move results file to a subdirectory: <code>mkdir $VERSION_DIR; mv *.txt $VERSION_DIR</code></li>
<li>Repeat from step 1 with a different configuration (e.g. <code>--js-flags="--nolazy"</code>).</li>
<li>Create the final results file: <code>./callstats.py json $VERSION_DIR1 $VERSION_DIR2 > result.json</code>
