+The page load metrics subsystem captures and records UMA metrics related to |
+page loading. This includes page timing metrics, such as time to first |
+paint, as well as page interaction metrics, such as number of page loads |
+aborted before first paint. |
+ |
+The page load metrics subsystem is not supported on iOS, as it requires hooks |
+into Blink for page timing metrics that are unavailable on iOS. |
+ |
+This component has the following structure: |
+- chrome/browser/page_load_metrics/: browser process code |
+- chrome/common/page_load_metrics/: code shared by browser and renderer, such |
+ as IPC messages |
+- chrome/renderer/page_load_metrics/ : renderer process code |
+ |
+For additional information on this subsystem, see |
