In one embodiment, the system includes an intermediary device, such as a web proxy, that receives client requests for content, such as requests for web pages. The device obtains the requested content, modifies it by applying one or more performance optimizations, and serves it to the client. The device also inserts code into the content for execution by the client to gather and report data reflecting, e.g., how quickly the client is able to get and process the content. The code includes information identifying the modifications the device made, and this is reported with the timing data, so that the effect on performance can be analyzed. In other embodiments, the device selects one of multiple versions of content, and the inserted code contains information identifying the selected version. The foregoing are merely examples; other embodiments are described herein."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Assessment of content delivery services using performance measurements from within an end user client application","description":"A system for measuring and monitoring performance of online content is provided.
