Scamper is a collection of RESTful libraries and frameworks, organized as a testbed for comparing the raw performance characteristics of each.

Each implementation exposes the same three endpoints:

• GET /fast blocks for 0 ms
• GET /medium blocks for 150 ms
• GET /slow blocks for 300 ms

Each endpoint responds with <h1>slept for { duration } ms</h1>, where duration is the actual amount of time spent blocking.

Each implementation runs on localhost:9000 and can be tested with a variety of tools, such as weighttp or JMeter.

Test results
