Latency

</a>
|
|
. JMeter measures the latency from just before sending the request to
|
|
just after the first response has been received. Thus the time
|
|
includes all the processing needed to assemble the request as well as
|
|
assembling the response, which in general will be longer than one
|
|
byte.
|
|
Protocol analysers (such as Wireshark) measure the time when bytes are actually sent/received over the interface.
|
|
The JMeter time should be closer to that which is experienced by a
|
|
browser or other application client.

Median
|

|

</a>
|
|
is a number which divides the samples into two equal halves.
|
|
Half of the samples are smaller than the median, and half are larger.
|
|
[Some samples may equal the median.]
|
|
This is a standard statistical measure.
|
|
See, for example:

|
<a href="http://en.wikipedia.org/wiki/Median">

The remaining samples too at least as long as the value.

This is a standard statistical measure.

The time is calculated from the start of the first sample to the end of the last sample.

This includes any intervals between samples.
