Yandex.Tank is a utility for load testing and performance analysis of web services and applications. Tank was developed at Yandex in 2006 for testing the banner system. Now it is one of the main tools for measuring performance.
The modular architecture of Yandex.Tank allows using various load generators. These include the high-performance asynchronous hit-based HTTP request generator Phantom and the scenario-based utility jMeter, which generates loads for different types of protocols.
