locust_fixed_interval

About

A Locust TaskSet that sends requests at a constant rate (with a fixed time interval). Based on Locust issue #646.

The instance 'interval' attribute defines the time interval between successive requests per user in seconds (default 1.0). This value must be greater than the average HTTP request roundtrip time. For example, if your request takes 1.9 seconds to get to the server and back, and the execution of your code and the Locust framework code additionally requires 0.1 second between requests, you should set 'interval' to a value over 2.0 seconds. If you need a higher request rate, increase the number of simulated users.
