Hi guys,
I want to find out the JavaScript execution details by V8. Anyone knows how to figure out v8 execute Javascript (real-world pages) in detail, i.e.
when interprets? when compiles?
For example, running a Telemetry benchmark with tracing:
$ tools/perf/run_benchmark --browser=android-chromium smoothness.top_25_smooth --story-filter=yahoo --output-format html --output-format json
then 4 html trace files and 1 json file are generated:
http___answers_yahoo_com22017-09-01_15-36-05.html
This trace file provides the overall JavaScript execution information, but not the details.
Title | Tab.ExecuteJavaScript |
User Friendly Category | other |
Start | 7,861.667 ms |
Wall Duration | 466.510 ms |
Self Time | 0.166 ms |
How can I get the information of JavaScript execution details? Do you have any advice for this?
Thanks in advance!
Best Regards,
Michael
