A non-transitory machine-readable storage medium encoded with instructions executable by a processing resource of a computing device to access network traffic exchanged with a web server application. The storage medium also identifies, in the accessed network traffic, an analysis reporting message of a client system and extracts, from the analysis reporting message, information representing a client system analysis of at least one prior transaction between the client system and a proxy server associated with the web server application. The information representing the client system analysis can comprise information describing an experience of the client system, including an indication of an amount of time to perform at least one prior transaction between the client system and the proxy server.
