This architecture allows Gatling to generate more throughput on one machine than other tools that use the [1 Thread: 1 VU paradigm]([[The 1 Thread=1 Virtual User Paradigm is flawed]]) - [[Akka framework]] is built for speed - On an 8-core machine, [[Stéphane Landelle]] [said]([[Load Testing Done Right using Gatling with Stephane Landelle]]) that Gatling can generate 100,000 rps with 1,000 VUs and 40 threads. ## Integration Since it's code-based ([[Scala]]), Gatling scripts excel at integration with IDEs, versioning, and continuous integration tools - very similar to [[k6 (Company)]] in that regard.
