Apache JMeter is a free and capable testing tool that can be used to load test the IdP. A simple parameterized test plan, shibboleth-unsolicited-sso-test.jmx, is attached to this page. The test flexes the authentication and SAML messaging subsystems to measure system throughput under common load patterns.
