US Patent 8005943 Performance monitoring of network applications

Network performance is monitored using timing information retrieved from a client device, server in communication with the client, or both. Client side timing information is retrieved using performance monitoring code provided by the server. The code may be provided to the client as part of a content response. Once content in the provided content response is loaded, the code sends the timing information to the server. The server may then process the timing information to calculate response time and other time information metrics.
