It might be less than 4kb, depending on the OS and JVM etc. > To overcome this issue I start a program inside a shell or prompt to get > latency statistics during the test. > > The concept of Latency is the elapsed time since the last byte sent and the > first byte received. Agreed. However JMeter only sees what the HTTP library returns, and that in turn depends on the JVM and the OS. If there is any buffering, then the first response to JMeter will be later than the first response from the network. Even the OS may not know when the first response occurs if there is buffering in the network card. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
