Usage

  1. Install scipy, e.g. sudo aptitude install python-scipy
  2. Build chrome.
  3. Check out a known working version of webpagereply:
git -C $CHROME_DIR/third_party/webpagereplay checkout 7dbd94752d1cde5536ffc623a9e10a51721eff1d
  1. Run callstats.py with a web-page-replay archive:
$V8_DIR/tools/callstats.py run \
        --replay-bin=$CHROME_SRC/third_party/webpagereplay/replay.py \
        --replay-wpr=$INPUT_DIR/top25.wpr \
        --js-flags="" \
        --with-chrome=$CHROME_SRC/out/Release/chrome \
        --sites-file=$INPUT_DIR/top25.json
  1. Move results file to a subdirectory: mkdir $VERSION_DIR; mv *.txt $VERSION_DIR
  2. Repeat from step 1 with a different configuration (e.g. --js-flags="--nolazy").
  3. Create the final results file: ./callstats.py json $VERSION_DIR1 $VERSION_DIR2 > result.json
  4. Use results.json on this site.
