The page analyzer analyzes your web page performance by emulating how a web browser would load your page and all resources referenced in it. The page and its referenced resources are loaded and important performance metrics are measured and displayed in a load-bar diagram along with other per-resource attributes such as URL, size, compression ratio and HTTP status code.

Load Impact generates simulated user traffic to your site – for example it might simulate that 50 users are trying to load your web pages at the same time. While simulating the traffic from these 50 users, it also records how fast pages are loaded from your server. This lets you know how fast your site is (as experienced by a user) when it is being accessed by 50 users at the same time.
