Runtime Stats Komparator

Usage

1. Build chrome with the extended runtime callstats.
2. Run callstats.py with a web-page-replay archive:

   ./callstats.py run \
           --replay-bin=$CHROME_SRC/third_party/webpagereplay/replay.py \
           --replay-wpr=top25.wpr \
           --js-flags="" \
           --with-chrome=$CHROME_SRC/out/Release/chrome \
           --sites-file=top25.json

3. Move results file to a subdirectory: mkdir $VERSION; mv *.txt $VERSION
4. Repeat from step 1 with a different configuration (e.g. --js-flags="--nolazy").
5. Create the final results file: ./callstats.py json $VERSION1 $VERSION2 > result.json
6. Use results.json on this site.
