## What it is
Tsung is a multi-protocol distributed load testing and benchmarking tool written in Erlang. It simulates thousands of clients to test the scalability and performance of IP-based client/server applications over protocols like HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP, MQTT, AMQP, and Jabber/XMPP.

## Use cases
- load test an HTTP web service with thousands of concurrent users
- benchmark an XMPP messaging server's scalability
- stress test a PostgreSQL or MySQL database under heavy query load
- simulate distributed traffic against an MQTT or AMQP broker
- measure performance of an LDAP directory server
- run distributed load tests from multiple machines

## When to choose
- you need multi-protocol load testing beyond plain HTTP
- you want distributed load generation from multiple nodes
- you need to benchmark messaging protocols like XMPP, MQTT, or AMQP
- you need very high concurrency thanks to Erlang's lightweight processes

## When to avoid
- you only need simple HTTP load testing with a modern scripting workflow (tools like k6 or Locust may be easier)
- you prefer writing test scenarios in a general-purpose language rather than XML
- you need a GUI-driven load testing tool
- your team has no Erlang/OTP operational experience
