That got recalculated during a performance recording:In the Performance tool, click the Capture settings () button, and then select the Enable advanced rendering instrumentation (slow) checkbox.DevTools displays aggregate information about the selectors of the CSS rules that were recalculated during the recording in the Selector Stats tab:In the Main section, select a Recalculate Style event. In the Selector Stats tab, DevTools displays information about the selectors of the CSS rules that were recalculated during that event.View messages between windows, iframes, and dedicated workersThe DevTools experiment Timeline: Show postMessage dispatch and handling flows improves the Performance tool's Main section to help you quickly identify postMessage events and handlers, by distinguishing events that are triggered by the postMessage method from other events that are displayed in the Performance tool. This experiment helps you investigate performance issues that are related to posting messages across various threads of an application.Without this experiment, events that are triggered by dispatching and handling messages between threads of an application appear as generic scripting function-call events. With this experiment enabled:postMessage dispatch events appear as Schedule postMessage.postMessage handler events appear as On Message:This experiment helps you investigate when a postMessage call occurred, and how long the message was queued before the postMessage handler starts. The dispatch events are linked to handler events by initiator arrows that appear when you click on either type of event:To use this feature, in DevTools, select Customize and control DevTools () > Settings > Experiments, select the checkbox Timeline: Show postMessage dispatch and handling flows, click the Close (X) button, and then click the Reload DevTools button.See also:Performance recording event referencepostMessage Trace Events demo (rendered)postMessage Trace Events demo (source code)Use the Rendering tool to help visualize the rendering performance of your page.To open the Rendering tool:To open DevTools, right-click the webpage, and then select Inspect.
