In an embodiment, a packet data switching system comprises content-addressable memory configured to redirect, to a measurement computer, a request to access a server application program hosted at a server computer in response to receiving the request from a client computer; the measurement computer comprises request rewriting logic configured to receive the request via redirection based on the CAM, to record a first time value representing a time of receiving the request, to forward the request to the server application, to receive a response from the server computer to the request, to rewrite a payload of the response by embedding a browser-executable measurement reporting script into the payload, and to forward the rewritten response to the client; performance recording logic configured to receive a second time value from the client based on the client computer executing the measurement reporting script, and to store a performance record with the time values.
