How Fast AI Correlation Changes Locust Scripting

Carrie and Rupert were so quick correlating Locust scripts that we slowed the video—not the AI—to narrate it. Here’s what that speed unlocks for performance engineers.

Performance testers know how long it can take to hunt dynamic values, build regex, test, and retry. In our latest clip, the AI agents Carrie and Rupert grab the values, validate them, and generate the correlation in seconds. The action was so quick we literally couldn’t narrate it in real-time—so we slowed the video down.

We slowed the clip down. Not the AI.

Why the speed matters

Correlation has always been a patience tax. When you can collapse that loop, three things happen:

  • You stay in flow instead of context-switching between regex testers and editors.
  • You can validate more hypotheses per hour—fewer brittle scripts ship to load test day.
  • You start experimenting with richer scenarios (think more auth flows, more edge cases) because setup isn’t a bottleneck.

What’s happening under the hood

In the demo, Carrie parses the Locust traffic, spots dynamic candidates, and drafts extractors. Rupert validates them across the run, wiring the correlation back into your tasks. The pair hands you an annotated plan so you can accept, tweak, or reject before code changes land.

Try it in your workflow

Upload a Locust script that normally takes you 20–30 minutes to correlate by hand. Let the agents run, review the proposed extractors, and ship. The delta you save is the headroom you need for designing better load profiles and assertions.

See how fast your own scripts can move.

Spin up a free trial, drop in a Locust script, and watch Carrie and Rupert handle correlation in seconds.
