It measures advanced web quality metrics show results on the console view, with options to save results to disk. It calculates the time instant metrics: DOM, PLT (onload), and ATF load time. It also calculates time integral metrics, similar in spirit to Google's SpeedIndex, but measuring load completion of objects (ObjectIndex), bytes (ByteIndex) and images (ImageIndex).
