The document discusses performance testing tools like JMeter and Gatling, highlighting issues related to usability, maintainability, and scalability in load testing. It promotes Gatling for its asynchronous programming model and rich domain-specific language (DSL) features, which simplify the testing process. Additionally, it mentions upcoming enhancements and integration options for better performance testing workflows.

4. 1 user = 1 thread

5. With 50 threads on a JVM

6. With 2000 threads on a JVM

7. Blocking I/O

8. Threads? Waiting…

9. … and sleeping

10. Is that a real problem?

11. Can you trust your results?
JMeter 2.8 perf test, expecting 300 tr/sec

12. Issue #2
Usability

13. Graphical User Interface
Listen, it's not that
complicated...

14. Issue #3
Maintainability

15. What was this change about?

17. Say hello to my little friend…
Version 1.3.5
Released November 2012

18. Be asynchronous, embrace the
actor model

19. Use non-blocking I/O
• Async HTTP Client
• Netty

20. Scenario
= Code (Scala)
= DSL

21. Easy

22. Use the rich DSL…
Checks
• regex / css / xpath / jsonPath
• find / findAll / count
• is / in / not / whatever
Structures
• doIf / repeat / during / asLongAs
• randomSwitch / roundRobinSwitch
Error handling
• tryMax / exitBlockOnFail
Feeders
• csv / tsv / jdbc

23. … or write your own Scala code…

24. …or use the Recorder

25. Integrations
• Maven Plugin
• Maven archetype (run in IDE)
• Graphite live reporting

26. Coming soon…
• Jenkins Plugin
• Requests Grouping
• Websockets, JDBC…
• Clustering

27. Demo

28. Really efficient?

expecting 300 tr/sec
