Difference in scripting time in devtools and Chrome

soulgalore opened this issue · comments

Hi Paul,
I've been trying out the devtools timeline (great work, it so nice to not parse the log) and it seems like scripting time is always low.

If I drag and drop the tracelog into Chrome 64 I get this:

screen shot 2018-01-25 at 5 24 30 pm

And from devtools-timeline-model (model.bottomUpGroupBy('Category').children):

{ rendering: 1851.997999727726,
        scripting: 303.46600019931793,
        loading: 120.90799987316132,
        painting: 51.13799995183945 }

Here's the trace I used: https://gist.github.com/soulgalore/1946f6d3ed8da35c904e14c08985e172

Seen the same thing on other pages too. Could the reason be that it depends on an old chrome-devtools-frontend?

Best
Peter

Hi. Can you share the code for getting the timings info from model.bottomUpGroupBy('Category').children?
