I'm currently writing integration tests for a RoR REST API using cucumber.
I'd also like to stress-test the API and was wondering how I might be able to re-use my cucumber scenarios to do this.
I've used JMeter and httperf before for stress-tests, and of course with both tools had to write or record the tests that I wanted to include in the stress testing. Since I already have the scenarios in Cucumber that I want to test, I'm trying to avoid having to rewrite what would be largely the same scenarios in the stress-testing tool's syntax.
Can anybody recommend a way that I could use my cuke tests for this? Ideally, I'd like to simulate hundreds of concurrent users hitting the API.

Performance Insights for Cucumber Tests tool provides an easy and reliable way to discover performance issues during early development, focusing only on the database operations. The tool executes a set of Cucumber tests that run through various code paths to measure the number of database operations.
Cucumber is an open-source software testing tool written in Ruby. Cucumber enables you to write test cases that anyone can easily understand regardless of their technical knowledge.
A stress test usually involves walking on a treadmill or riding a stationary bike while your heart rhythm, blood pressure and breathing are monitored. Or you'll receive a drug that mimics the effects of exercise.
Gherkin is Cucumber's language parser, which allows software behaviours to be specified in a logical language that people can understand. This means that Cucumber feature documentation is written in business-facing text that is non-technical and human readable for stakeholders like business analysts and managers.
You very well may have to create your own load harness. Essentially, you'll need to start up a number of threads, each calling the process to start your scenarios. You will want to have a delay to stagger when each thread starts because there will be some overhead involved with loading the Ruby interpreter. You may also have to spread the load across more than one machine for the same reasons. It would probably be best to do this in separate processes. Perhaps this might be good for a new project?
