Abstract

A device receives a list of uniform resource locators (URLs), selects a web page URL from the list of URLs, and requests, via a browser application, content corresponding to the selected web page URL. The device also receives, via a packet capture, a web page associated with the selected web page URL, derives performance information associated with the packet capture, parses the packet capture to extract page level statistics, connection level statistics, and inline object level statistics, and stores the page level statistics, the connection level statistics, and the inline object level statistics to output files.
