Time to First Buffer Breakdown (Over Time) Graph
This graph displays each Web page component's server and network time (in seconds) during each second of the load test scenario run, for the period of time until the first buffer is successfully received back from the Web server.
Note: This graph is only relevant when the load generator does not use a proxy to connect to the application under test. If the load generator is connected through a proxy, this graph will only show the proxy latency—not the AUT latency.
You can use this graph to determine when during the scenario run a server- or network-related problem occurred.
Elapsed time from the beginning of the scenario run.
Average network or server time (in seconds) for each component.
Note: Because server time is being measured from the client, network time may influence this measurement if there is a change in network performance from the time the initial HTTP request is sent until the time the first buffer is sent. The server time displayed, therefore, is estimated server time and may be slightly inaccurate.
