<li>
Click "Start" to start number crunching. This will take a while.
</li>
<li>
Click "Show plot/profile" to switch between the statistical profile and
the timeline plot.<br/>
C++ items are missing in the statistical profile because symbol
information is not available.<br>
Consider using the
<a href="https://code.google.com/p/v8/wiki/V8Profiler">
command-line utility
</a> instead.
</li>
</ol>
If you expect multiple V8 instances to run concurrently, for example
with several tabs in Chrome,<br/>
add the V8 flag <span class="tt">--logfile=v8.%p.log</span>
so that each instance writes to its own log file.
