Unless the system clocks are reasonably well synchronised, combining results can cause problems for throughput calculations, as the elapsed time may be adversely affected. Also, note that the same test is run on each server node, so running with a single JMeter server instead of two will result in running half the number of samples. You may find it better to use two independent non-GUI runs and combine the results later. > --------------------------------------------------------------------- > To unsubscribe, e-mail: > [email protected] > For additional commands, e-mail: > [email protected] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
