This figure shows the execution phases for a request in the HTTP server, including handle time, connection time, and request time. On the left, a user submits a request. The total connection time is shown on the top. The connection time consists of the total of the request phase, and the handle phase. The figure shows that the duration of a connection may be much longer than the time required to perform a request and return a response. This is because the connection may remain open while a single client submits multiple requests and those requests are handled
