What is the use of pacing in LoadRunner?
Pacing is used to regulate the rate of requests hitting to the server. Using Pacing, you can accurately achieve the required TPS rate against your system instead of just mindlessly hammering it. Pacing creates a realistic scenario which adds more accuracy in the performance test result.
What is rendezvous point in LoadRunner?
A ‘Rendezvous point’ is a single and simple function in a VuGen script that instructs load runner (during a test with multiple users) to wait at a specified step in the script till all the Vusers (executing the script) come to that step so that subsequent request can be executed simultaneously.

- Reserve a timeslot.
- Run the test.
- View and analyze test results.
What is difference between think time and pacing?
Pacing in load testing refers to the time between the iterations of your test scenarios. This is unlike Think Time, which refers to the delay between actions or interactions inside iterations. Pacing allows the load test to better simulate the time gap between two sessions.
What is performance testing of a web application?
A performance test is any test that measures stability, performance, scalability and/or throughput of your web application. It is used to ensure the final build meets the expectations of an end user and helps a business achieve its objectives.
