Rendezvous point instruct vusers to wait during test execution for multiple vusers to arrive at a certain point, in order that they may simultaneously perform a task.
v users execute the script whenever they get the time slot. In this process some vusers may reach end of the script while other vusers may not have yet started. So to stop the execution of vusers untill all the vusers reach at a particular point and execute all at a time we insert rendezvous point.
rendezvous point is a work place where all users gathered and released at a time to perform their task on the application. this is used to increase load on the application, to observe how application is working(to measure performance) at peak stages, and to know bottle neck point.
Rendezvous point is Synchronization point which helps us to synchronize all the vusers and stops them at that point before executing the subsequent transactions. The significance of this is to emulate some heavy load only to particular portion of the scenario and experience the behaviour of the application.
It is a Interrupt point .It stops current vuser script execution until all v_user scripts are executing up to that point. This point is defined load balancing.
