The Page Speed tab can be used to analyze the active website. A website optimization report will be generated that groups the findings into priorities. The high and medium priority groups list elements that should be optimized to increase the performance of the website. Low priority items on the other hand are fully or partially optimized items that can still provide some performance gains but not as much as the medium or high priority items.

Each entry is listed with a short description, priority and an expanding area that lists the elements that are affected and optimization tips on how to resolve the issue. This usually requires some research on how to implement the optimization, the Page Speed homepage is usually a good starting point as it contains some tips on how to resolve some of the issues. Some issues cannot be solved by the webmaster at all, like compressing or combining externally loaded JavaScript.

The Page Speed Activity tab on the other hand displays a timeline of all browser activities including JavaScript processing which makes it easier to spot scripts and elements that are increasing the loading times.

The data is divided into blocks that define elements like network latency, DNS lookups, connection establishment, and JavaScript processing.
