tsung

distributed multi-protocol load testing tool

Tsung is a distributed load testing tool. It can be used to stress HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and Jabber/XMPP servers. The purpose of Tsung is to simulate users in order to test the scalability and performance of IP based client/server applications. You can use it to do load and stress testing of your servers. Many protocols have been implemented and tested, and it can be easily extended. WebDAV, LDAP and MySQL support have been added recently (experimental). For HTTP, it support 1.0 and 1.1 version, has a proxy mode to record sessions, support GET and POST method, Cookies and Basic WWW-authentication. It also has support for SSL. It can be distributed on several client machines and is able to simulate hundreds of thousands of virtual users concurrently (or even millions if you have enough hardware ...).
