???????????￡???????????Run-Time Settings??????Think Time????????????????????????????????????????????????????????????
????By default?? when you run a Vuser script?? the Vuser uses the think time values that were recorded into the script during the recording session. VuGen allows you to use the recorded think time?? ignore it?? or use a value related to the recorded time:
????Ignore think time. Ignore the recorded think time—replay the script ignoring all lr_think_time functions.
????Replay the think time. The second set of think times options let you use the recorded think time:
????As recorded. During replay?? use the argument that appears in the lr_think_time function. For example?? lr_think_time(10) waits ten seconds.
????Multiply recorded think time by. During replay?? use a multiple of the recorded think time. This can increase or decrease the think time applied during playback. For example?? if a think time of four seconds was recorded?? you can instruct your Vuser to multiply that value by two?? for a total of eight seconds. To reduce the think time to two seconds?? multiply the recorded time by 0.5.
????Use random percentage of the recorded think time. Use a random percentage of the recorded think time. You set a range for the think time value by specifying a range for the think time. For example?? if the think time argument is 4?? and you specify a minimum of 50% and a maximum of 150%?? the lowest think time can be two (50%) and the highest value six (150%).
????Limit think time to. Limit the think time's maximum value.
