Pacing in performance testing refers to controlling the rate at which virtual users execute transactions to simulate real-world user behavior.

• Pacing helps in simulating realistic user behavior by controlling the rate of transactions executed by virtual users.

• It is calculated by dividing the total test duration by the number of transactions to be executed.

• For example, if a test is scheduled to run for 1 hour and 600 transactions need to be executed, the pacing would be 1 trans...read more

Distributed load testing involves simulating multiple virtual users from different locations to test the performance of a system under heavy load.

• Involves simulating virtual users from different locations

• Tests the performance of a system under heavy load

• Helps identify bottlenecks and performance issues

• Commonly used in web applications and APIs

Ramp up and ramp down are performance testing terms referring to gradually increasing or decreasing the load on a system.

• Ramp up is the process of gradually increasing the number of virtual users accessing a system over a period of time.

• Ramp down is the opposite process of gradually decreasing the number of virtual users accessing a system over a period of time.

• Ramp up and ramp down help in simulating real-world scenarios where the load on a system gradually increases or decr...read more
