Iago

Written mostly in Scala, Iago was developed by Twitter to test an application's responses to huge traffic loads.

Iago will not only generate the fake traffic, but in some cases will also log the application's responses as well.

This project is perfect for engineers working on important projects that need heavy testing before being releasing their code to production environments.

Features:

• Tested with more than 100K requests per second
• Support for custom, exponential or uniform traffic distributions
• Documentation
• Supported services:
• HTTP
• Thrift
• Memcached
• Kestrel
• UDP

Requirements:

• Scala 2.9.2 or higher
