A Cautionary — and Inspiring — Tale

“Writing another load test tool? What a stupid idea!” That’s how it all started — out of frustration with limited or overpriced existing solutions. But what began as a questionable decision turned into a powerful open-source load and performance testing tool: Xceptance LoadTest – XLT.

In this engaging and insightful talk, you’ll hear the real story behind building a tool that now powers over 150 projects a year. From costly mistakes to critical design decisions, the speaker shares 17 years of hands-on experience in the Java ecosystem — no sales pitch, just hard-earned lessons and practical insights.

If you’re an engineer or performance tester with a basic understanding of load testing, this session will take you on a journey through real-world challenges, open source contributions, and the evolution of a tool born from necessity.

Don’t miss this chance to find out whether writing your own tool is genius — or just plain crazy.
