1494608 - Frame Construction markers take so much time for marker allocation

Status: RESOLVED FIXED

(Core :: Gecko Profiler, enhancement)

Description

[Nazım Can Altınova [:canova][:canaltinova on phabricator]]

Currently we have both markers and profiling labels for frame construction. But in a Slack conversation, jesup said that the profiler_tracing method takes over %10 of time in the frame constructions and he can't take a very long sample of Speedometer without it taking forever to load the profile. It's because there are so many ContentAppended/Removed markers in the profile. We should remove the markers and keep the profiling labels instead.

Markers are taking so much time(~10%) to allocate and in a website
like Speedometer, it takes ages to load the profile data since
there are so many frame construction markers.
