The Grinder is a Java load-testing framework that makes it easy to run a distributed test using many load injector machines.

Grinder key features:

  • Generic Approach: Load test anything that has a Java API. This includes common cases such as HTTP web servers, SOAP and REST web services, and application servers (CORBA, RMI, JMS, EJBs), as well as custom protocols.
  • Flexible Scripting: Tests are written in the powerful Jython scripting language.
  • Distributed Framework: A graphical console allows multiple load injectors to be monitored and controlled, and provides centralized script editing and distribution.
  • Mature HTTP Support: Automatic management of client connections and cookies. SSL. Proxy aware. Connection throttling. Sophisticated record and replay of the interaction between a browser and a web site.
