Run V8 with
Chrome with --no-sandbox --js-flags="--prof --log-timer-events" to produce v8.log.
- Open v8.log on this page. Don't worry, it won't be uploaded anywhere.
- Click "Start" to start number crunching. This will take a while.
Click "Show plot/profile" to switch between the statistical profile and
the timeline plot.
C++ items are missing in the statistical profile because symbol information is not available.
Consider using the command-line utility instead.
add the V8 flag --logfile=v8.%p.log so that each instance writes to its own log file.
