What is the criteria for selecting tools to test Performance?
There are a many products available for load testing a Web server and it is important to select a tool that suits the hardware and OS environment. The load testing tools must support:
- Simulation of any number of clients and users
- Simulating HTTP 1.0 as well as HTTP 1.1 clients
- Simulating user sessions using new cookies or re-using existing cookies
- Simulating authentication when required
- Capturing the response codes and detecting correct responses based on error responses
- Working in a distributed manner
Working in a distributed manner is useful if the load cannot be simulated from a single client machine. In distributed mode, the data and metrics are automatically collected from all agents running on different machines and presented at a central place.
Important: Do not have the Load Simulator and the ‘System Under test’ running on the same machine. This will eat up the system resources. It is important to convert the test to a stand-alone Java client and run it from a separate machine.
