We use this for fixed delay in response like giving 500ms delay for each request.
```{
    "request": {
        "method": "GET",
        "url": "/delayed"
    },
    "response": {
        "status": 200,
        "fixedDelayMilliseconds": 2000
    }
}```


Yes, I know this feature. But what I want is get the same response time in every call. So, instead of delay a constant time should be injected.

No answer but let me give a solution to this. I wished to get a 50 ms average response time. My response transformer extension class that builds the whole response had a 15 ms processing duration. So I set a fixed 35 ms delay. This way, I could achieve a 50 ms average time. Our aim was specify an average response time of our visualized external service so we could isolate the external service and measure the performance of the desired real service.
