Talos is a versatile cross-platform Python performance testing framework. It was created to serve as a test runner for the performance tests that Mozilla was running back in 2007, as well as providing an extensible framework for new tests as they were created.

So, why Talos? Talos is the bronze automaton of Greek myth. Talos protected the island of Crete, throwing giant boulders at unwary seamen. He's also purported to have heated himself glowing hot and then embraced his enemies. Basically, he was awesome.
