People often ask what are the differences between RBUs and VUs. Obviously RBUs are more realistic while VUs are the perfect vehicle for testing APIs, but here is a table giving you a breakdown.
| Feature | RBU | VU |
|---|---|---|
| Threads | 6 threads downloading data in parallel | Single thread downloading data in sequence |
| Ajax | Native support and simple to implement | Can be scripted but takes time |
| Flash | Has ability to test Flash interaction | Flash objects can be downloaded, but won’t be played |
| Reporting | Screen-shot of failed page captured; error codes from server | Content of last requested object captured; error codes from server |
