For instance, the graph above shows the transaction performance times for two
transactions. You can see that each time the transaction was executed,
performance time decreased. If you compare this graph to the Running Virtual
Users graph, you can see that the performance time improved because the Vuser
load decreased.
Note that the transaction times are only indicated by the peaks in the graph. When
running multiple Vusers, one transaction may begin before the previous one ends,
resulting in a continuous line. The line does not indicate the actual start and end
times of transactions; it is only a mechanism used by the graph to join the peaks.
The Transaction Performance graph may be displayed using different granularities.
The y-axis represents the average transaction response time within the granularity
interval. For example, for a granularity of 1, the
y-axis
shows the average response
time for each one second period of the scenario. For a granularity of 2, the
y-axis
shows the average response time for every two second period of the scenario.
