During a scenario run, you can instruct multiple Vusers to perform tasks simultaneously by using rendezvous points. A rendezvous point creates intense user load on the server and enables LoadRunner to measure server performance under load.
Suppose you want to measure how a Web-based banking system performs when ten Vusers simultaneously check account information. To emulate the required user load on the server, you instruct all the Vusers to check account information at exactly the same time.
You ensure that multiple Vusers act simultaneously by creating a rendezvous point. When a Vuser arrives at a rendezvous point, it is held there by the Controller. The Controller releases the Vusers from the rendezvous either when the required number of Vusers arrives, or when a specified amount of time has passed. For details on the release criteria, see “Setting the Rendezvous Policy”.
You define rendezvous points in the Vuser script. For information about inserting rendezvous points into Vuser scripts. Using the Controller, you can influence the level of server load by selecting:
For example, to test a bank server, you could create a scenario that contains two rendezvous points. The first rendezvous ensures that one thousand Vusers simultaneously deposit cash. The second rendezvous ensures that another thousand Vusers simultaneously withdraw cash. If you want to measure how the server performs when only five hundred Vusers deposit cash, you can deactivate (disable) the “withdraw” rendezvous, and instruct only five hundred Vusers to participate in the “deposit” rendezvous.
The following procedure outlines how to control load peaks on the server:

You can set the following rendezvous attributes from the Rendezvous Information dialog box (Scenario> Rendezvous):
