Some time ago Federico Toledo published Performance Testing with Open Source Tools- Busting The Myths. That’s when we decided to go for a name that would first be available but also avoiding a “load-something” name (I know 10 of these, not even counting LoadRunner/NeoLoad) while integrating the notion of performance.
