Viewing page response time contributions - Legacy Reports

You can display the response time contributions for individual page elements in reports, to determine how much time each page element contributes to the overall page response time and to determine which page elements are performance bottlenecks.

About this task

Because page elements can be returned in parallel from the server under test, the page response time is not necessarily the sum of the page element response times. Client delay and connection time also contribute to page response time. The page response time can be greater that the sum of the page element response times if, for example, a lengthy connection time adds a delay. Connection time includes the time required for Domain Name Services (DNS) lookups. Conversely, the page response time can be less than the sum of the page element response times if multiple page elements are returned in parallel. To view page element response times, which do not include client delay or connection time, see Viewing page element responses.
