Use of single control flow to support multiple network connections for server load testing

Abstract From the Canadian patent

A load testing system (100) for testing a web site or other type of server system (122) uses a thread architecture that reduces the computing resources needed to generate a desired load. The load testing system runs several virtual users (102) on one or more clients (104) to simulate user interactions with the server. Each virtual user is executed as a virtual user thread (112) under a process on a client computer. Each virtual user thread itself establishes and supports multiple connections (202) to the web site; therefore, an additional thread need not be created for each connection. For each connection, the virtual user thread performs a sequence of functions in an asynchronous …
