Comment on attachment 222291 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=222291&action=review r=me, looks fine I'd be worried about a lot of extra / duplicated data being sent to the frontend. Also it would be really great to include a test for this. LayoutTests/inspector-protocol/timeline/profiler-data-in-script-execution.html or something like that. > Source/WebCore/inspector/InspectorTimelineAgent.cpp:338 > + RefPtr<ScriptProfile> profile = ScriptProfiler::stop(toJSDOMWindow(frame, debuggerWorld())->globalExec(), ASCIILiteral("Timeline EvaluateScript")); > + TimelineRecordFactory::appendProfile(entry.data.get(), profile.release()); Seems like we could be duplicating a bunch of data sent to the frontend? It seems nested ScriptProfiler::start/stops are fine, but each time it stops it sends an entire profiler, much of which could be data already captured and sent in another profile? I know you measured, what was the performance impact of this? > Source/WebCore/inspector/TimelineRecordFactory.cpp:257 > + data->setValue("profile", profile->buildInspectorObjectForHead()); Nit: ASCIILiteral("profile")
