XML configuration system; several sessions can be used to simulate different type of users. User think-times and the arrival rate can be randomized using a probability distribution.
A script storyboard provides a graphical view of test scenarios; the scripting interface enables script customization.
Load injectors can be installed on your own network or on the cloud.
Locust - Scalable user load testing tool written in Python.
Locust is completely event-based, and therefore it's possible to support thousands of concurrent users on a single machine.
HTML reports can be generated during the load to view response times measurement, server CPU, etc. Loadster - Load testing tool from Brickyard Technologies, Inc.
