Tsung is a distributed load testing tool. It is protocol-independent and can currently be used to stress HTTP, WebDAV, PostgreSQL, MySQL, LDAP, AMQP, and XMPP/Jabber servers. It simulates user behavior using an XML description file, reports many measurements in real time (statistics can be customized with transactions, and graphics generated using gnuplot). For HTTP, it supports 1.0 and 1.1, has a proxy mode to record sessions, supports GET, POST, PUT, and DELETE methods, cookies, and basic/digest authentication. It also has support for SSL, WebSocket, and BOSH.
irssi-xmpp is an irssi plugin to connect to the Jabber network. It aims to provide good integration in this text-based IRC client. It can send and receive messages in irssi's query windows. A roster is shown for tracking contacts' resources. Contacts can be managed. Command completion, multiple accounts (in different connections), Unicode, and SSL are supported.
