Bristlecone provides tools for testing database performance. There are two main tools included in the package.
* Evaluator generates mixed loads of inserts, updates, deletes, and selects. Output can be built-in graphics, HTML, XML, or CSV.
* Benchmark runs performance test cases with systematically varying parameters. Output can be HTML or CSV.

The Bristlecone tools were designed for comparative evaluations of database clusters. They include built-in support for threading, ability to generate new tests quickly with simple configuration file changes, and the ability to do systematic tests across different database implementations. Bristlecone is written in Java. It has mostly run on Linux but is easily adaptable to other platforms. Bristlecone has been tested against the following database types: PostgreSQL, MySQL, and HSQLDB (Hypersonic).
